Ballet buffs—please help me ID some music from a van Dantzig/Nureyev ballet

I know that Rudi van Dantzig’s ballet, About a Dark House, (which was written for Rudolf Nureyev) has music by Roman Haubenstock-Ramati. But what I don’t know is what the actual compositions by Haubenstock-Ramati are called. One of my clients, a photographer, is trying to track down their titles (and some recordings) for a presentation he’s doing.

Anyone have an idea?
