I just want to say the from a drummers perspective, Portnoy IS THE MOST OVERRATED DRUMMER EVER!!!!!!!!!!!
I can play nearly everything he can, but somehow everyone thinks he's god. The fills and solos he plays are actually very basic once you break them down. His double kick is often uneven too. Shit, he can't even play doubles with one foot.
Rullo is my favorite metal drummer over Portnoy because his fills are much more solid and he's more tasteful than just pounding the shit out of the set. Portnoy needs to learn that there is something called dynamics. I guess that Portnoy being the frontman of DT lets him get away with all the crazy fills and nonsense. Just because he plays more doesn't mean hes a better player.
However, Dave Dicenso is my favorite drummer off all time at this point. He's a teacher at Berklee College of Music. He was in the Cro-mags and did some stuff with Duran Duran, plus some other solo shit. But he's playing on Petrucci's solo album. Check out some of his solo's at
