The story
Early Red Hot Chili Peppers albums (1984–1987)
The band changed its name to the Red Hot Chili Peppers, playing several shows at L.A. venues. Their repertoire grew to nine songs as a result of months of playing at local nightclubs and bars. The Red Hot Chili Peppers entered Bijou Studios to record a demo tape produced by the then-drummer of Fear and subsequently secured a record deal with EMI. Irons and Slovak, however, decided to leave the Red Hot Chili Peppers in order to pursue a "more serious" future with the rock band What Is This? Flea ultimately respected the decision, but felt the band would be lost without them. He and Kiedis hired drummer Cliff Martinez and guitarist Jack Sherman to fill Irons' and Slovak's place, respectively. Andy Gill, formerly of Gang of Four, agreed to produce their first album. Gill and Sherman clashed with Flea and Kiedis; they continuously argued over music style, sound, and the album's production. Flea himself felt that the album was stiff and "a big mistake", but also admitted, "we [he and Kiedis] were just disrespectful and obnoxious." The band's debut album, The Red Hot Chili Peppers, was released on August 10, 1984, to largely poor critical and commercial review. After a relatively unfruitful tour, Sherman was fired in early 1985. Slovak, who had been contemplating a return to the Chili Peppers, rejoined the group after being encouraged by Flea.
Funk musician George Clinton was hired to produce the band's second album, Freaky Styley (1985). The strong chemistry between Clinton and the Chili Peppers was felt instantly. Flea later referred to Clinton as "the warmest, kindest man in the world". Freaky Styley was released in August 1985. It received only a bit more attention than The Red Hot Chili Peppers with roughly 75,000 copies sold by year's end. Flea was somewhat indifferent to the poor album sales as he had recently proposed to girlfriend Loesha Zeviar, who was pregnant with their child. The band hired Michael Beinhorn, their last resort among potential producers, to work on their next album. Irons' band What Is This? had finally disbanded, and he returned as drummer to the Chili Peppers in mid-1986 after Martinez was fired. Flea, Slovak and Kiedis especially were involved in heavy drug use and their relationships became strained. Flea recalled that "it began to seem ugly to me and not fun; our communication was not healthy". Kiedis became dependent on heroin, leaving Flea and Slovak to work on much of the album's material by themselves.
Kiedis was briefly kicked out of the band and given a month to rehabilitate. Kiedis completed the rehab and returned with the Red Hot Chili Peppers in Los Angeles to record their third album The Uplift Mofo Party Plan (1987). Flea has referred to the album as "the 'rockingest' record" the band has ever made. The Uplift Mofo Party Plan proved to be far more successful, commercially and critically, than the Chili Peppers' preceding albums, registering at number 148 on the Billboard 200. Following the Uplift tour, Slovak's drug use dramatically increased. Flea's relationship with Slovak faded, and Slovak became isolated and depressed. On June 27, 1988, Slovak was found dead of a heroin overdose. Flea reflected: "I didn't really know how to deal with that sadness, and I don't think [Kiedis] knew how to deal with it either." Irons, who was taking Slovak's death particularly hard, left the group.
Flea and Kiedis took some time to collect themselves, but they kept the band together. Guitarist DeWayne "Blackbyrd" McKnight and drummer D.H. Peligro were added, and the band entered the studio to record a new album. McKnight soon began to create tension within the group, as his style did not mesh with the rest of the band. Peligro, the former drummer of the punk rock band Dead Kennedys, was a friend of John Frusciante, an 18-year-old guitarist and avid Red Hot Chili Peppers fan. Peligro introduced Frusciante to Flea, and the trio jammed together on several occasions. Flea was impressed with Frusciante's skill, and astonished by his knowledge of the Chili Peppers' repertoire. Flea realized that Frusciante could provide the spark McKnight was lacking. McKnight was fired, and Frusciante accepted an invitation to join the band. Peligro was fired shortly thereafter; the Chili Peppers brought in drummer Chad Smith as his replacement.
Mainstream success and side projects (1989–1998)
Flea and his wife Loesha started to grow apart, and he began trying to recreate the memories of his adolescence by smoking marijuana on a daily basis. The Chili Peppers entered the studio, and completed recording of their fourth album, Mother's Milk, in early 1989. Upon release, the album was met with mixed reactions from critics, but received far more commercial attention, peaking at number 52 on the Billboard 200. After this, Flea made appearances playing the trumpet on Jane's Addiction's 1988 album Nothing's Shocking, and bass on the critically acclaimed 1989 Young MC album Stone Cold Rhymin'. He would also appear in the video for "Bust a Move", the hit single from the same album.
The Mother's Milk Tour put further strain on Flea's marriage. In order to make money, he needed to tour, and therefore spent time away from his family. Furthermore, he and Smith were arrested on charges of battery and sexual harassment after a performance on MTV's coverage of spring break; charges were eventually dropped. The band was, however, attracting over three thousand people per show; Mother's Milk had been certified as a gold record in early 1990. By the time Red Hot Chili Peppers returned to Los Angeles, Flea and Loesha agreed to a separation. He tried to put the separation out of his mind by smoking marijuana and having sex with random groupies, when the band was on tour for Mother's Milk.
When the successful Mother's Milk tour was over, the Red Hot Chili Peppers severed ties with EMI and signed instead with Warner Bros. Records. Rick Rubin, who had rejected an opportunity to produce The Uplift Mofo Party Plan, agreed to produce their next album. Flea had largely used the principal slap bass technique on the band's preceding four albums, and decided to downplay this style in favor of more conventional, melodic bass lines. To record the album, Rubin suggested they use a mansion that once belonged to magician Harry Houdini. Flea felt it was "a creatively fertile situation", and decided to bring his daughter Clara with him. He and the rest of the band, excluding Smith, remained inside the house for the entire recording process. When not writing or recording the album, Flea spent a large portion of his time with Frusciante smoking large quantities of marijuana. The emotions Flea felt during the album's recording were like nothing he had ever experienced:
When we [the band] made Blood Sugar Sex Magik we spent a lot of time jamming—every day, for hours and hours. I remember during that time Anthony went off and made a movie, and for a long time it was just me, John and Chad, and we'd just go in there and play. Me and John were hitting the bong and we just rocked and grooved forever. It was the first time we went in to make a record where there wasn't this feeling of being sort of intimidated by what was going to happen.

When Blood Sugar Sex Magik was released on September 24, 1991, it received an extremely positive critical response. The album peaked at number three on the Billboard Hot 200, and went on to sell over 7,000,000 copies in the U.S. alone. The album's ensuing tour was critically acclaimed—the Chili Peppers commonly performed shows with over 20,000 in attendance. Seattle-based grunge band Nirvana also toured with them during the West Coast leg of their United States tour. The massive attention the Chili Peppers started receiving, however, caused Frusciante to feel extremely uncomfortable, and he abruptly quit the band during the Japanese leg of the album's tour, replaced temporarily by Arik Marshall. Following the tour in 1993, Flea was diagnosed with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and was ordered to rest for a year.
On October 30, 1993, Flea was playing at The Viper Room with the band P when his close friend River Phoenix was outside the venue having seizures as the result of an overdose. When this news filtered through the club, Flea rushed outside and accompanied Phoenix in the ambulance that took him to Cedars-Sinai Hospital.
Flea and Kiedis felt it best to fire Marshall due to lack of chemistry and briefly replaced him with Jesse Tobias, although his tenure was very short and he was quickly replaced by Jane's Addiction guitarist Dave Navarro, who was once recruited in 1992 to replace Frusciante. The band was ready now to record their next album although Kiedis was in the middle of a heroin relapse, which forced Flea to assume the role of lyricist, something he had not yet done. He wrote most of the song "Transcending", and the intro and outro to "Deep Kick". Flea also wrote the entire lyric to a song, "Pea", in which he both played bass and sang. These three songs appeared on the Chili Peppers' sixth record One Hot Minute, which was released on September 12, 1995. The album received mixed reviews and was significantly less commercially successful than Blood Sugar Sex Magik. The One Hot Minute Tour was ultimately cut short due to various injuries Kiedis and Smith received, and the Red Hot Chili Peppers decided to go on hiatus. Flea was so miserable that at one point during the tour he discussed quitting the band. Flea began to practice Transcendental Meditation and yoga, and slowly decreased his marijuana consumption. Due to the Chili Peppers' inactivity, Flea joined Navarro in a Jane's Addiction reunion tour in 1997, filling in for ex-Jane's Addiction bassist Eric Avery. Rumors spread, that the band was breaking up until Navarro stated otherwise: "I want to clarify that the Chili Peppers are not breaking up... Flea and I are more than happy to do both projects, time permitting."
Flea also had plans to record a solo album. He asked Chili Peppers manager Lindy Goetz to help him promote the record and his future solo career. Flea eventually abandoned the idea in favor of offering his bass services to other artists. He performed on over forty records from 1995 to 1998, ranging from Alanis Morissette's Jagged Little Pill (with Navarro) to former Minutemen bassist Mike Watt's debut solo album Ball-Hog or Tugboat?. He also worked with Tori Amos and Michael Stipe on a track for the soundtrack to the 1995 Johnny Depp film Don Juan DeMarco. Navarro was fired from the Chili Peppers in 1998, and Flea questioned whether or not the Red Hot Chili Peppers would stay together: "... the only way I could imagine carrying on is if we got John [Frusciante] back in the band." Frusciante had completed drug rehabilitation in 1997 after a severe addiction to heroin and crack cocaine left him on the brink of death. Flea visited Frusciante in early 1998, inviting him back to the Chili Peppers; an emotional Frusciante readily accepted.
Californication, By the Way and Stadium Arcadium (1998–2007)
With Frusciante back on guitar, the band began writing new songs during the summer of 1998 in Flea's garage. He and Kiedis were less confident in writing the album after the disappointing results of One Hot Minute. Flea had also recently broken up with his girlfriend of two years, Marissa Pouw, causing him to enter a state of depression which was only lifted when his daughter, Clara who was 10 years old, comforted him after several weeks of crying.
Flea was heavily influenced by electronica during the writing and recording of Californication (1999) and he attempted to emulate this when writing bass lines for the album. Californication took less than two weeks to record; by contrast, One Hot Minute took over a year. When Californication was released on June 8, 1999, it received overwhelmingly positive critical reviews and sold fifteen million copies worldwide—more than Blood Sugar Sex Magik. The Chili Peppers played Woodstock 1999, with Flea playing completely naked—something he would do again at the Reading and Leeds Festivals the same year as well as several other Californication tour concerts.
Red Hot Chili Peppers spent most of 2001 writing their eighth studio album, By the Way (2002). The band began listening to more melodic, textured music, that would reflect heavily on the album. Frusciante became the driving force behind By the Way, causing initial strife between him and Flea. If he introduced a funk rhythm into his bass lines Frusciante would consequently disapprove to the point where Flea almost quit the band because he felt his role was no longer important. By the Way was released on July 9, 2002, to positive reviews, and went on to sell over nine million copies worldwide. The ensuing tour was extremely profitable; the Chili Peppers performed three concerts in London's Hyde Park to over 250,000 attendees and a total gross accumulation of US$17.1 million. It became the highest grossing concert at a single venue in history.
After another two-year world tour, the Chili Peppers wrote their ninth studio album, Stadium Arcadium (2006). Unlike By the Way, both Flea and Frusciante were more musically conjoined when writing the record. They found inspiration in Jimi Hendrix, Jimmy Page, and Eddie Van Halen among others. The double album was ultimately released on May 9, 2006, to generally positive reviews, selling over seven million copies in less than two years. In November 2007, Flea's $4.8 million Corral Canyon home in Malibu burned down in a wildfire. The location was not, however, his primary residence, and at the time of its destruction was being rented to musician and producer Butch Walker.
Return to school, Atoms for Peace, I'm with You, and Rocket Juice & the Moon (2008–2011)
After the Chili Peppers announced a long hiatus due to exhaustion, Flea enrolled in music classes at the University of Southern California, where he studied music theory, composition and jazz trumpet. Flea attributed his interest to a newfound desire to widen his appreciation and understanding of music: "It's so much fun to learn this stuff because I never knew anything. I played trumpet in the school bands. I learned things I liked to play on my trumpet but I didn't learn why this note goes with this note and why it produces that sound. Or how to create tension in the composition [...] Knowing the structure is really fun." Flea said he planned to release a mainly instrumental solo record, recorded in his home, with guest musicians including Patti Smith and a choir from the Silverlake Conservatory.
In 2009, Flea joined Atoms for Peace, a supergroup formed by the Radiohead singer Thom Yorke to perform songs from Yorke's debut solo album, The Eraser (2006). Flea and the band recreated Yorke's electronic music with live instrumentation. They toured the United States in 2010, and released an album, Amok, in 2013. Amok was followed that year by a tour of Europe, the US and Japan.
The Chili Peppers ended their hiatus in October 2009 without Frusciante, who quit the band to pursue other musical interests. He was replaced by Josh Klinghoffer. The Red Hot Chili Peppers released their tenth studio album, I'm with You, on August 29, 2011. Also that year, Flea played bass on two songs on Tom Waits' album Bad as Me, released on October 21. On October 27, 2011, it was announced that Flea's project with Damon Albarn and afrobeat drummer Tony Allen would be called Rocket Juice & the Moon. The band made their live debut on October 29, 2011, in London, and released an album on March 12, 2012.
In a June 23, 2011, interview, Flea discussed the band's return and how he almost quit the Chili Peppers during their hiatus. Flea said that he wanted to take two years away to see if the band was "something we should still be doing.... Things had gotten dysfunctional and not fun, even though I thought we were making great records, doing great shows and were a really powerful, mighty thing as a band. I was proud of what we did.... For me, the biggest thing during the time off, and what really made me want to continue doing the band, specifically after [he] decided he didn't want to continue in the band anymore, [was] I just realized, Anthony, man, he's my brother, I love him so much, and we started this band when we were kids. I wanted to keep that going, I never want to let that go. Playing with him is something, even though I can do other things that are exciting and beautiful and I always will do those things and I'll always want to grow and do music outside of the band, the thing that we have is special to us and something that is blood."
Rock and Roll Hall of Fame induction, Helen Burns, The Getaway, and memoir (2012–2019)
The Red Hot Chili Peppers were inducted into the Rock and Roll Hall of Fame in April 2012. Flea said: "It's always been easy for me to pooh-pooh these awards—the [Rock] Hall of Fame too. But I inducted Metallica a couple of years ago, and it was really a beautiful thing to see as all these people were being inducted. It made me love it. I love halls of fame anyway—the Basketball Hall of Fame, the Baseball Hall of Fame. So I feel grateful for the recognition of what we have done and for the hope and potential of what we'll continue to do."
On July 19, 2012, Flea released a solo EP, Helen Burns, composed mainly of instrumental tracks, except the title track (which Patti Smith sang on) and "Lovelovelove", which features the Silverlake Conservatory of Music's kids and adults choir. It is Flea's first solo release, as he had previously released solo songs only on soundtracks and other projects. Flea said of the EP, "I am putting it out to raise money for the Silverlake Conservatory of Music, a community-based non-profit music school that I am an integral part of." The download of the EP is available at "a name your own price" on the Silverlake Conservatory website and was made available through all major digital outlets on August 9, 2012.
On October 16, 2012, his 50th birthday, Flea gave an interview with CNN discussing the Chili Peppers and was asked if he plans to continue with them. Flea responded by saying "I love the Chili Peppers, and I would love to. If there's anything I know, it's every time you start making plans, you don't know what's going to come up next. Anything can happen. So I love being in the Chili Peppers and it's my home, and I've been doing it for more than half my life. Of course, during the course of doing it, there's been all kinds of ups and downs, and moments of extreme (positivity), floating on clouds of greatness, and times of just groveling, and misery, and uncertainty, and anger, and love and all those things. Like being in a family. I really can't predict. But I love being in it for now, and right now, about as far as I'm thinking is getting through this tour that we're doing, performing at the highest level possible, then hunkering down and writing another record."
On April 9, 2014, it was revealed that Flea was working on a new musical project, the band Antemasque, with former Mars Volta members Cedric Bixler-Zavala, Omar Rodríguez-López, and Dave Elitch. Two songs were released in early April, although Flea has confirmed that he is not a member of the band and just recorded a few songs with them. Antemasque released their self-titled debut album on July 15, 2014.
In February 2015, Flea posted photos on his Instagram page showing that he had broken his arm during a skiing trip. His injury delayed the recording of the Chili Peppers' eleventh studio album for six months. Production was expected to resume in mid-August according to Flea, who said on August 3 that he was healed enough to play bass again and continue recording. The Chili Peppers released their eleventh studio album, The Getaway, on June 17, 2016. The band embarked on a 151-date world tour which concluded in October 2017.
Flea released his long-awaited memoir, Acid for the Children, on November 5, 2019. Flea first began the writing process in April 2014. The original scope of the book was to chronicle Flea's unconventional childhood (including his move from a "normal" life in the New York suburbs to a "bohemian" lifestyle in Los Angeles with his jazz-playing stepfather), his adventures in the L.A. streets, his "sometimes complex friendship and collaboration" with Chili Peppers co-founder Anthony Kiedis and the overall "tumultuous creative journey" of the band, which formed in 1983.
Unlimited Love, Return of the Dream Canteen and Honora (2020–present)
In December 2019, the Red Hot Chili Peppers announced that guitarist John Frusciante would be returning to replace Josh Klinghoffer. The band then focused on preparations for making a new album, which they originally hoped to have released in 2020, along with performing on a few festival dates. The Chili Peppers began working on their twelfth studio album in the summer of 2020; however, due to the COVID-19 pandemic, there were delays in the writing and recording, with their 2020 tour dates being postponed until 2021.
In August 2020, Flea appeared on two unreleased songs from River Phoenix's band Aleka's Attic to mark what would have been his 50th birthday.
In the same month, Flea was featured playing bass on multiple tracks on the Bright Eyes studio album Down in the Weeds Where the World Once Was.
In January 2021, it was announced that Flea and John Frusciante contributed a cover of "Not Great Men" to the upcoming tribute album to Gang of Four titled The Problem of Leisure: A Celebration of Andy Gill and Gang of Four. The double album was released on June 4, 2021.
In October 2021, the Chili Peppers announced the dates for their 2022 world tour that began in June 2022 and will conclude in July 2024. The tour includes the band's first-ever headlining stadium shows in the United States in support of their twelfth and thirteenth studio albums, Unlimited Love and Return of the Dream Canteen, which were released on April 1 and October 14, 2022, respectively.
Flea, along with Josh Klinghoffer and Chad Smith, collaborated with Morrissey on his upcoming album Bonfire of Teenagers, which was supposed to be released in February 2023. However, in December 2022 it was announced that its future was in limbo, as Capitol Records has decided not to release it. On May 16, 2025, it was reported by Deadline that a documentary on the Red Hot Chili Peppers' formative years was being secretly screened at the Cannes Film Festival and was looking for select buyers in both New York and Los Angeles. A festival premiere for the film was to be planned for either fall 2025 or early 2026. The documentary, which is being co-produced by Hillel Slovak's brother James, will center on the deep childhood bond between Flea, Anthony Kiedis, and Hillel Slovak, and features various interviews from current and past band members.
Flea performs trumpet on the song "My Plane Leaves Tomorrow (Au Revoir)" on Al Jardine's 2025 EP, Islands In The Sun. Neil Young is also featured on the song. On December 4, 2025, Flea released "A Plea", the first single (with a music video directed by his daughter Clara Balzary) from his debut solo album Honora, which is due for release on March 27, 2026 on Nonesuch Records. The album features six original songs and four cover songs along with appearances by Thom Yorke and Nick Cave. The second single, "Traffic Lights", featuring Yorke, was released on January 14, 2026, along with an animated music video. Flea embarked a small tour in May 2026 to promote the album.
In February 2026, Flea confirmed that the Chili Peppers are currently in the writing process for their fourteenth studio album. “We’ve been writing music together, recording at John Frusciante’s house, and the music feels great. Ultimately, once we start playing, it’s about… just catching a magic groove and doing it good." Flea performed on The Tonight Show Starring Jimmy Fallon on March 23, 2026.
