I am watching the film right now and I just realized that it's been 35 years now. It's a brilliant score and I think it deserves a proper (cough*FSM*cough) anniversary treatment along with Kilar's score!
It's actually a good album musically (performance and music included), but the sound is excruciatingly shrill, and it gets worse on an unforgiving high end system. So, we either need drastic improvement in the sound with remastering, or a complete new recording. Based on the quality of John Mauceri's performance of a brief excerpt ("Night Journeys") on his Hollywood Nightmares album, he would be an excellent conductor for a complete new recording.
