I figured some of you folks might want to know about this if you hadn't heard of it already. J Randall from Agoraphobic Nosebleed just finds albums that he wants to promote and helps bands release their stuff digitally for free.
Bands worthy of mention that I have found were Wadge, Cloud Rat, Eustachian. I also want to check out the Robocop and Bestower albums. There are some ANb b-sides, but ultimately it's a crapshoot in terms of quality, but there are some really cool things like dueling live sets between bands or remix albums for bands you never heard of. Just find a cool album cover or band name and download it. It won't hurt you.
