The list of the best drummers playing today is short...it starts and ends with Mike Portnoy. The rest of the discussion is for the "next best".
In terms of pure technical capability, I agree 100%. Watched Score last night on the plane. EVERY song amazes.
Danny Carey (Tool) manages to arrange much better, though, while still showing off his chops. He is my favorite drummer to listen to, with Peart a close second. Joey Jordison and Matt McDonough are also fun to listen to. Copeland's unqiue
approach to drumming is what sets him apart as one of the greats. The same can be said for Moon.
From the one and done bin, Chad Kent played with the now defunct Atomship and wrote one of the best drummer centric albums I've ever heard (and that's primarily what I buy)
Finally, if Living Colour is serious about making a comeback, Will Calhoun immediatly jumps into the top 5 list of current rock drummers.
