wow....
Somone obvioulsy owns a good sub... i get the flutter on my headphones of the low ranges you're using... i can't wait to get home to listen to this on a better setup... I know you're going for dubstep, but it could do with a tiny little bit more pace in places, just to pull it up a notch or two.
Great piece of work, and as a loop it's cool... i've been listening to it for a while now and didn't even notice :D
Can't wait for the release, this is a great WIP
