Query: Klaus's first solo

...and actually, it's not a solo at all. Klaus Schulze here appears with a string orchestra on this album, recorded during a hiatus from Ash Ra Tempel. But don't expect your typical synth + orchestra New Age here; "Irrlicht" is a droning, dark, bleak offering, with the depth and breadth of interstellar space in its sound. From the classic 'kosmische musik' period of German electronics, this album will be a startling revelation to those accustomed to Schulze's later sequencer-based work of the 1970s and early 80s, or the MIDI-based work dating from the mid-80s and on. But those interested in a real musical adventure will love "Irrlicht".
