ミュジーク・コンクレート
In 2005, Schulze said, ""Irrlicht" still has more connections to Musique concrète than with today's electronics. I still never owned a synthesiser at the time." Schulze mainly used a broken and modified electric organ, a recording of a classical orchestra rehearsal played backward, and a damaged amplifier to filter and alter sounds that he mixed on tape into a three-movement symphony.
