Kluster were a short lived "band" that existed in the early 1970's, formed by Conrad Schnitzler after he left Tangerine Dream, and at the height of what we now refer to as "Kraut Rock". Comprising Roedelius, Moebius and Conrad Schnitzler, they were together long enough to record and release three albums, all in editions of between a few hundred and five hundred, and all of which are today extremely hard to find collectors items that, when found, usually go for hundreds of dollars each. Conrad left Kluster after their third album "Eruption". Roedelius and Moebius have continued under the name Cluster, with dozens of releases already out under this name.
