So, after all this modern classical/avant-garde stuff, I thought of recommending something on the 'popular' side of things.
Minimal Man - The Shroud Of (1981)
Visual and performance artist at core, Patrick Miller aka Minimal Man, is one of the more interesting musicians of the very exciting late 70s post-punk/avant-garde/electronic San Francisco scene, art punk or industrial punk if you prefer it. This is his first album which I very much recommend for its relentless haunting power.
EDIT: The new poll is open!
