Hans-Joachim Roedelius and Dieter Moebius parted ways with Conrad Schnitzler to form Cluster in 1971. Their improvised music proved ground breaking in terms of structure and timbre, mostly composed by treated instruments and electronic means. After leaving Berlin, they settled in Forst, Lower Saxony, and built a home studio, which fostered collaborations with many musicians, including Michael Rother, Conny Plank. Brian Eno and Mani Neumeier.
Guitarist, sound architecht and composer, Michael Rother is one of Germany's original artists of the progressive era. In the mid 1960s, he was a member of Spirits of Sound with Wolfgangs' Flür and Reichemann, then a member of Kraftwerk, Neu!, and Harmonia until forging a very successful solo career (with Jaki Liebizeit and Conny Plank) towards the late 1970s through the early 1980s.
