They performed cover versions of John Mayall, Jimi Hendrix and Led Zeppelin in local venues and disbanded after making a few radio recordings and several concerts.

After few member changes the band finally made in March 1974 to be their first major recording, "Sen o dolinie" as the Polish cover of Bill Withers' "Ain't No Sunshine".

In autumn 1974, they recorded "Cień wielkiej góry", inspired by death of Polish mountaineers Zbigniew Stepek and Andrzej Grzązek in the Himalayas in 1973.

This record saw some contributions from Czesław Niemen, who played his Moog synthesizer psychedelic parts in a majestic rock suite called "Szalony koń".

He has only appeared on few records ("Rozmowa", "Kula nocnego światła", "Ślady na piasku", "Życiowy numer"), then unreleased and quit soon after.
