I just picked up a copy of Cluster & Eno, the collaborative effort between Brian Eno and the electronic Krautrock duo Cluster recorded in 1977. It’s beautiful, atmospheric music that doesn’t seem blah or prog, and it’s delightfully repetitive even though there were no sequencers used, just echo machines, tape recorders, guitars, bass (sometimes played by Holger Czukay of Can), and of course, “early polytone Farfisa synthesisers!”
Here’s a little documentary about Cluster’s early days. Boy, I wish I had that many cool noise boxes on top of my Farfisa!
