This is a bit of a shameless promotion really but its for a good cause.
DJ Hiem of Pittsburgh PA recently survived a bout of cancer and has put together a compilation where the profits are donated to cancer research. This is not something you'd typical see from mainstream music either, and it is a worthy enough cause. For 20 bucks you get 4 cds with exclusive mixes in a rather nice case, and you are helping to further cancer research. The compilation is called Electronic saviors. Link included below
