The back catalogue of this mystical and mercurial German collective, numbering Messrs Moebius and Roedelius from Cluster as well as Neu's Michael Rother in their ranks. has always been frustrating only in its brevity, and with that in mind this live material from their heyday is as manna to krautrock enthusiasts - these at once meditative and exploratory voyages through inner space bear all the hallmarks that made their two studio efforts such evergreen portals to a fertile age of experimentation and inspiration, and an inspration to Eno and Bowie amongst a legion of others - Sehr kosmisch, indeed.
