Irrlicht, (subtitled "Quadrophonische Symphonie für Orchester und E-Maschinen"; English: Will-o'-the-wisp: Quadraphonic Symphony for Orchestra and Electronic Machines) is the debut solo album by Klaus Schulze, originally released in August 1972 on Ohr Records. Recorded without synthesizers, Irrlicht's set of "early organ drone experiments" is "not exactly the music for which KS got famous".[2] In 2006 it was the sixteenth Schulze album reissued by Revisited Records as part of a series of Schulze album reissues.
Irrlicht's atmospheric drone music tone is similar to Tangerine Dream's album Zeit, released the same year. In 2005, Schulze said, "Irrlicht still has more connections to Musique concrète than with today's electronics. I still never owned a synthesizer at the time."[3] Schulze mainly used a broken and modified electric organ, a recording of a classical orchestra rehearsal, and a damaged amplifier to filter and alter sounds that he mixed on tape into a three-movement symphony.[3]
Irrlicht, despite its highly unconventional nature, was originally released on the krautrock label Ohr. Because Schulze was signed to them while a member of Tangerine Dream, the label asserted that his solo album belonged to them too;[3] Schulze's reaction was, "I was just glad that Irrlicht was released at all. Any other company would have probably turned me away with this record."[3]
