The group was formed in autumn 1969 and was apparently the first ever creator of art-rock music in Czechoslovakia. The core of the largest and most intense touring productivity formed the Marian Varga, bassist Fedor Fres and drummer Dušan Hájek. With the shorter breaks the group worked on the music scene in 1979.
