The story
Opus was founded in 1971 and spun off as the Slovak division of music label Supraphon. As such, it was the first Slovak record label. It was privatized in 1990 and purchased by Forza Music s.r.o. in 2005. When Warner Music Group acquired Forza in 2019, they expected to revive the Opus label for pop, rock, and children's music. The label is active to this day and operates under the name Opus a.s.
In addition to Slovak, and later Czech, artists and bands, the label also published works by foreign artists from countries including Poland, Hungary, East Germany, Yugoslavia, and Greece.
