Groundbreaking Electronic Music by Stuart Porter (July 30, 2003)
I've got the originally released soundtrack on CD, not the full score by Wendy Carlos. I'm not a massive lover of classical music, but these electronic interpretations are interesting, and the abridged sections of original classical music fit in well, and represent memorable scences from the film. Of course, the Moog derived sections sound very dated now, but still very listenable. The album also works OK if you haven't seen the film.
