The electronic pioneer Hans-Joachim Roedelius is a legendary figure in popular music. He founded the seminal bands Cluster and Harmonia, which also included Dieter Moebius and Michael Rother. He produced the albums "Zuckerzeit" (1974) and "Deluxe" (1975), which are considered blueprints for today's electronica and were recently successfully reissued. And in the late 70s he worked with the great Brian Eno – the albums "Cluster & Eno" (1977), "After The Heat" (1978) and "Tracks & Traces" (1997) document the cooperation between the Bowie and U2 producer and the sound researcher who was then living in a creative commune in Forst.
