Duul to the death
Amon Duul II, Vive La Trance (United Artists 1974)
I don't know much about the specific history behind this particular arm of the krautrock constellation but if you're looking for another Tago Mago or Popol Vuh this isn't it. Weird record -- the Duuls are looking very RenFaire on the back cover and the music is a mish-mash of glam, folk and avant-prog that still yields up a couple of interesting jams.
