One of Germany's first experimental rock groups, Agitation Free was a part of the scene in Berlin in the late 60s. Members included Michael Hoenig and Chris Franke, Axel Genrich, Lutz Ulbrich and many other notable musicians. Their legacy however is some of the most listenable music of the era.
The original "Wohngemeinschaft" from Munich, Amon Düül's mixture of politics and music were born straight out of the 60s. Musically, however, it's unessential listening. All releases were culled from recording sessions held in 1968.
Led by Chris Karrer, the musical half of the Munich commune hippie band of the same name; a little to rough around the edges for prog standards, but most certainly not to be overlooked; Amon Düül II are Germany's finest psychedelic sons.
Member of Tangerine Dream's classic lineup, Peter Baumann emigrated to the US, where he went on to become a great producer and label-head of Private Music. He is currently the founder and director of The Baumann Foundation, a San Francisco-based think-tank on the human condition
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.
