From the BBC:
The late 1960s and early 1970s saw in West Germany the formation of an extraordinary handful of experimental groups, including Amon Düül 2, Can, Kraftwerk, Neu! and Cluster. These groups were often misunderstood and even ignored, not least in their own country, and in the UK were banded together under the term ‘Krautrock’, which they understandably resented. Today, the Krautrock groups are regarded as having exercised a huge influence on subsequent generations and genres including techno, post-punk, electropop, ambient and ‘post-rock’. However, perhaps the strangest of all of these avant-garde outfits, certainly the one with the strangest back story, is Faust, who formed in Hamburg and released their debut album on the German Polydor label in 1971.
