Don Ellis did an incredible job on the soundtrack. The moody character theme (titled Rounds and Spheres) was even released as sheet music (a goosebump-inducing live version is available on youtube). I'm hoping this music will one day be released, although I'm guessing it might be a while, considering how unimportant the movie is generally considered to be.
I do remember this movie, and have it on DVD. There was one cue that stood out in particular, and I can't tell you where in the movie it appeared, but I can describe it as a sort of victory cue of some kind. Might be time to watch this again!
I've always loved this score, and had hoped for a soundtrack album. It might make a great two-fer if placed onto a CD with some other appropriate score.
