For me, the single best Can album, even though it's an archival live compilation. Encompassing the years from 1973 - 1975, we catch Can at their most inventive, entirely within an instrumental mindset. Only the near 19 minute opener features the familiar Damo ranting, and even then, the majority of the track features an overt instrumental jamming motif. Otherwise it's psychedelic guitar, organ, bass and drum jams - wild, woolly and unpredictable - exactly what you would want to hear from a Krautrock legend. Well, OK true, Karoli puts in a few words on Geheim, but it's easy to overlook. A phenomenal anthology of work. A must own CD.
Worth noting that there are double LP reissues floating about on the "Strange Fruit" label, but it appears they are pirate editions. So be careful out there! Stick with the CD and never look back.
