Good call - he has a few cracking tunes on the new Dubstep Allstars complilation. Rusko's essential mix from 2008 was alright enough, but quite tame compared to what I would usually go for. His new stuff is fucking atrocious. I preferred him when he was making tunes like Action Dread. This is a decent remix:
Other worthwhile metions are Kromestar, Headhunter, RSD and Pinch. For the more brutal side, these guys always go down well for me: YouTube - Pixel Fist - Get Down - Rocstar
