I reckon, you should try to form a band with that much success, that includes one of the best drummers in the world, when you've done that come back and bitch about them.
Slipknot isn't to my taste in music, but I recognise their talent.
Actually I think you'll find success has nothing to do with talent. I have no musical talents and I am not successful in the music industry. Pointless comment that has nothing to do with the issue. But it all comes down to the fact that people won't listen to your music unless you are heavily marketed, play mainstream music and signed to a major label.
