Bunuel's amalgam of angular rhythms, drum salvos, blitzkrieging guitars and vocals that sound more like threats than promises is post-punk, proto heavy and arty up the ass. Arty as in avant-garde noise.
Cluster's self-titled debut was originally released by Philips in 1971; this edition is the first reissue to restore the track running order of the original Philips release. Includes liner notes by electronic avant-garde pioneer Asmus Tietchens.
