Paul Schütze – New Maps of Hell (1992) Full album
The first 20 minutes is wicked Avant Garde Jazz. The rest is something that might please the Ambient peoples with a Tribal Ambient interest. I think the entire album is a work of art. It may take a few listens to sink in. Bandcamp has a better sound quality preview.
I don't think Paul ever achieved much commercial music success, but suspect he does pretty well with high brow music for art installations these days.
