Cluster was the pioneering German duo of Hans-Joachim Roedelius and Dieter Moebius. Formed on the cusp of the 1970s, they were a part of West Germany's nascent Kosmische Musik scene. The group would use restrained improvisational techniques similar to Gruppo Nuova Consonanza, working with both electric and acoustic instruments (organ, guitar, tone generators, cello, etc.) to create a singular sound that Julian Cope called "a huge beating heart, planet-sized and awesome."
