I'll have to check out that movie. I've never even heard of it. I'm a fan of early electronic from Kraftwerk and the like. I never really got into Tangerine Dream though I am familiar with them.

It often gets lumped in with Sci-Fi movies but it is really an occult/horror film. Very atmospheric, very moody but well-paced (IMO).
Boo!
Just be prepared for a VERY dated presentation circa mid 1980s a la Michael Mann. Dramatic lighting, slo-mo, montage-type themes, etc. You get a glimpse of it in the clip I posted above.
The analogue synthy atmospheric sounds of TD enhances that 80's vibe almost to the point of making the movie seem like 80s caricature. But the story is super unique, the plot unfolds in some surprising ways, and there are a few scenes where the imagery is very visionary.
Great performances by Jurgen Prochnow, Scott Glenn, Ian McKellan, and Gabriel Byrne. I've always liked Prochnow, and his performance in this is great.
