This release sees the initial collaboration between the electronic duo Cluster and NEU! multi-instrumentalist Michael Rother, with the result being perhaps one of the best examples of the Krautrock form. This release, along with the more flowing and poppy "Deluxe", takes the industrialisms of early Cluster and the driving rock mechanisms of NEU! and splices them together to concoct a very satisfying artifact. Stuttering electronic rhythms sit alongside alternately tranquil and creepy ethereal ambiences here, making this an excellent look at the mid-70s German scene prior to Kraftwerk's "Autobahn" and its blowing the doors open to this style of music. Those interested at all in the early days of electronic pop MUST own a copy of this.
