The amount of artists and the volume of their output available on-line is absolutely overwhelming. That said, here's my input:
Bandcamp page - contains full albums and excerpts from upcoming albums.
http://sleepsessions.bandcamp.com/Soundcloud - contains demo tracks, works in progress and excerpts from single tracks (compilation submissions, etc.)
http://soundcloud.com/sleepsessionsAll of it is pretty straightforward cut-up harsh noise. No philosophy attached.
