Singing like Maynard - Any specific tips ?

Maynard of Tool/Perfect Circle. I don't know that any amount of practice will get me close.. (?) Him singing Passenger with the Deftones in good surround song..

None that I know of. Just hunch over and give it all you've got. Moving around like you're having convulsions seems to help him! LOL I'm j/k. Maynard is freaking awesome. Good luck with that.
