A rather short (about 20 minutes) but great early 80s electronic soundtrack, sounding a bit like early John Carpenter work but more twisted and dark. A crickety drum machine (probably a CR-78 or CR-8000) provides a thin, synthetic backdrop for both lush and sharp eerie dark room synth tones. Highly recommended, I just wish it was about twice as long at this kind of quality.
So now the search begins for the original film!
