Happy New Year!
Usually the Soundtrack of the Week is something that's actually been released as an album of some sort that you can listen to. For #250, however, no such document exists, and if it did it would probably only be about six minutes long. But we're picking the score for Punishment Park because it's by the great Paul Motian.
The music appears to be Paul Motian solo, mostly playing a couple of cymbals and/or gongs, a drum or two and what sounds like the inside of a piano or a zither or something like that. His score is similar to Toru Takemitsu's work, not only in what he actually plays but in how much space he leaves. There is very little music in the movie, which suits its documentary style.
