I have some bootlegs of early Pink Floyd (sadly in poor quality) doing that cacophonous thing, which was pretty much inspired from AMM's contemporaneous London performances.
Metal Machine Music, hell yeah - pre-industrial, pre-PE, still sounds great. Likewise VU obscurity 'Loop' and all those Dream Syndicate things.
'O Superman' is a wonderful record and was much loved by Dennis Nilsen according to his biographies, he'd sit with a dismembered body in front of him drinking and crying with that on headphones!
The comment by 'justinbsfavoritegurl' under that Black Sheep track is pretty funny.
