Yohann Schmitt of France. This kid's going to be the next generation Vinnie.
Also, Andrew Fisenden of Australia. Brilliant young funk drummer, borrows heavily from 70s/80s funk-fusion while keeping things simple with a ?uestlove type set-up. Steve Smith played with him during a festival and said, to the effect, "He's already a monster."
Has anyone heard Nick Pierce who played with The Faceless? This guy is phenominal. I saw him last year on tour with them. He plays insane speed and technicality using traditional grip. Last I heard he was going to try out for The Black Dahlia Murder. I'm sure he will go far. Check him out on Youtube. http://www.youtube.com/watch?v=eOYT3TjwRkU
As far as up and coming, it would be hard to say. I don't know any bands that are that new. Now as far as any drummer I've learned from, I would have to say Thomas Lang. He is, in my opinion, the most inovative, most creative and most technical drummer drummer around. Basically, I think he's a god at what he does.
