Amon Düül II (or Amon Düül 2) is a German rock band. The group is generally considered to be one of the founders of the German rock music scene and a seminal influence on the development of Krautrock. The band emerged from the radical West German commune scene of the late 1960s, with others in the same commune including the future founders of the Baader-Meinhof Group (the Amon Düül II band members disagreed with their violent agenda). Founding members are Chris Karrer, Peter Leopold, Falk Rogner, John Weinzierl and Renate Knaup. Their first album Phallus Dei (God's Penis), released in 1969, is considered a milestone in German rock history. They received offers to write music for films, winning a German film award, the Deutscher Filmpreis, for their contribution to the film San Domingo. Their second album Yeti was their breakthrough album in the United Kingdom. In 1975, they signed with Atlantic Records, and disbanded in 1981. Wikipedia
All great bands eventually reunite: and so it was, 14 years after their last, rather dull attempt at an album, the “original” line-up of “Amon Duul II” (with no Weinzierl who was off doing who knows what at this time) gets together to show the world they still have it nearly 30 years after their debut and 20 years after their last great album.
"Vortex" was the first and also the only album the band recorded in the 80th. Renate Knaup, Chris Karrer, Daniel Fichelscher, Jorg Evers and Falk U. Rogener, and the "guests" Lothar Meid, John Weinzierl and Stefan Zauner met 1981 in the studio too try it again. With "Vortex" they wanted to show, that there is still that old magic in the music of Amon Duul II. Songs like `Wings Of The Wind', `We Are Machine', `Vibes In The Air' or `Holy West', are comparable with all the Duul-Classics.
