The Swedish pop quartet's record label started the studio in 1978 and the group recorded its last three albums there. But the first big album recorded at Polar Studios was Led Zeppelin's "In Through the Out Door" in 1978.

Hundreds of bands and solo artists followed, including the Backstreet Boys (news - web sites), Genesis, the Beastie Boys, the Cardigans and Roxette — making Polar Studios a hot spot on the international music scene.
