Which band from Iceland was Bjork a part of in the 80's?

The Icelandic band Björk was part of in the 1980s was The Sugarcubes.

The Sugarcubes formed in Reykjavík in 1986 after members of Icelandic groups including Kukl came together. Björk Guðmundsdóttir served as the band's lead vocalist and keyboardist, while Einar Örn Benediktsson provided vocals and trumpet. Their energetic mix of alternative rock, post-punk, and avant-pop made them one of Iceland's first internationally recognized alternative bands.

The group's first English-language single, "Birthday," appeared in 1987 and attracted attention in the United Kingdom. Their debut album, Life's Too Good, followed in 1988 and became an unexpected international success. Its distinctive sound introduced many listeners to Björk before her solo career became globally prominent.

The band was sometimes identified by its Icelandic name, Sykurmolarnir, which translates as "The Sugarcubes." The Sugarcubes eventually disbanded in 1992, after which Björk pursued her highly influential solo career.
