Classic riff rock from Germany, 1970; lady singer, Renate Knaup, caterwauling dark gothic prophecies. Amon Duul ii emerged out of a post-'68 Berlin art commune, and are often initially confused (or by non-Germans, anyway) with Amon Duul, a competing splinter group from the original commune (who actually didn't start recording until after Amon Duul ii had already recorded several albums) and by most accounts are mediocre at best. At any rate, Amon Duul ii's album Yeti is stone-cold classic Krautrock. Histrionic pirates on sonic prog adventures into riffology, pastoral landscapes, and free rock music racket. And, likewise, their first album, Phallus Dei (1969), is an experimental rock juggernaut.
(Original Amon Duul ii's bassist, Dave Anderson, joined Hawkwind for 1971's In Search of Space.)
