Agitation Free was one of the leading representatives of German experimental rock music in the early 1970's. From the end of 1967, the Berlin band developed long, unusually free instrumental improvisations for that time. It achieved cult status in the early '70s with its unique mix of improvised rock with elements of electro, ethno, jazz and trance elements. Although a number of albums, recorded from 1972 to 1974, were released after the group's dissolution, it took almost 35 years for the original band to reunite and now they present their studio album 'Momentum,' their first album since 'River Of Return' from 1999.
