I watched 30th Century Man yesterday. I knew of Scott Walker, but not much of his work. I was blown away by this documentary, how he went from "MOR slop" to his "avant-garde art-rock".
Using a garbage can with a terra cotta pot on top, and a slab of meat for percussion...indescribable. This is going to need a repeat viewing down the line, there's a lot to take in in this piece in only 90 minutes.
