Sort through your obscure collections and recommend me some stuff?
I love most of the classic grindcore bands (Napalm Death are obligatory aren't they?), noise bands (I love a lot of Japanese noise bands, they're amazing. The Boredoms/Hanatarash are just scraping the surface?) and avant garde improv (anything completely wild associated with the new york jazz-fusion scene...lots of screaming, screeching sax's etc)
