Most people here hate Slipknot so I wouldn't expect much feedback, dude.
I'm no musician but I'd say that was some good drumming. Even non-Slipknot fans tend to admit that Jordison is an excellent drummer so, if you can mimic him, I guess that's pretty impressive
The song is shit, as are the band, but your drumming is very good.
I would hate to be in a band with you though, I'd be paranoid you'd drop a stick with all the tossing them around carry on
