Ennio Morricone - L'istruttoria e Chiusa: Dimentichi (1971)
An interesting recommendation from "Anonymous" in the Sweet Body Of Deborah comments. Although it's light years away from the kind of Morricone stuff I usually post, The Case is Closed, Forget It! (as it's also known) is still worthwhile for those who want a more challenging listen. This soundtrack is experimental and abstract and shows another side of the great Morricone.
