While Western Europe was going through a musical renaissance of sort with progressive rock bands blossoming in every land, the former Soviet Eastern block and its satellite border nations were somewhat left out of the game although there are many bands that bucked the censorship and attempted to create some of the music that was considered a threat to the control systems set up. One of these bands was a Polish group named KLAN which formed in 1969 Warsaw and along with Anawa and Czes?aw Niemen, was one of the earliest Polish bands to exhibit true full developed progressive rock qualities. KLAN has also been considered on of the best example of Poland's early prog movement however due to the pioneering ambitions never managed to released more than a single self-titled EP in 1970 and its only full-length MROWISKO in 1971. The title means "Anthill."
