Portnoy and Lombardo are on my list
One other drummer that not many people have heard of is Ted Kirkpatrick, he plays for a christian metal band called
Tourniquet He's definately my number one drummer. Their "Stop The Bleeding", "Psycho Surgery" and "Vanishing Lessons" are kick ass cds. The last couple they put out, haven't been as good.
I just went to their website to see what I could show you and see that they recently released a DVD with his drum solos and other stuff, I'm ordering it right now

If you wanna see some kick ass drumming, pick it up, I promise you, you'll be blown away.
Here's a link to the movie trailer of the dvd, you can get a little idea of what he's like. I wish that it showed a little more though -
