Grauzone (German for “grey area”) was a Swiss group formed in 1979 who played ten concerts and recorded four singles and one album before splitting up at the end of 1982. They are most famous for their amazing 1981 song “Eisbär” (“Polar Bear”). Ladytron samples the song on “Fighting In Built Up Areas” and it was also covered by French group Nouvelle Vague.

Grauzone would be considered a classic band of the ““Neue Deutsche Welle” era. They also left behind some music videos.
