Walter Carlos - Walter Carlos' Clockwork Orange (1972)
As contrived as it sounds, classical music helps me stay somewhat productive, so what better than 70s moog renditions of Beethoven's 9th? Wendy (formerly known as Walter) Carlos, best known for her Bach interpretations and Tron soundtrack, wrote this album for the Kubrick film. Though composing a series of autonomous pieces with an affinity for clockwork, most of Carlos' material was omitted from the film and its corresponding soundtrack.
On a completely unrelated note: anyone else have a Dieter Moebius death scare today?
