Amon Düül II

Amon Düül II was one of the most influential krautrock conglomerations, with members constantly flowing in and out and branching into other groups and new musical territory. This particular period, around the release of Yeti (1970), turned out to be a seminal moment in the history of the group, marking the beginning of their underground success outside of Germany. The album shows a remarkable breadth of expression, from strange, trance-like moments of noise, constrained acoustic ragas and improvisations, to explosive, dirty, electric prog with slamming beats and tape effects.

Amon Düül II

Amon Düül II grew out of an improvisational music collective that had been known simply as Amon Düül, a musical counterpart to a larger communal society in Germany. As Amon Düül became somewhat more cohesive, the name change to Amon Düül II happened in 1969 and more albums were recorded. Many members of the group flowed in and out of circulation and played with other bands as well.

Tangerine Dream

spanning 5 decades, Tangerine Dream is one of the most influential electronic groups out there. Alongside others like Kraftwerk, they catapulted the popularity of krautrock outside of Germany into the stratosphere in the late 60's and 70's. They continued on (with a few lineup changes) into the 80's and 90's experimenting with what became known as "New Age" music, and they're still out there today touring every once and a while.
