Well as far as favorite drummer, there are two classifications i look for...if your asking about drummer with the band (not in solos) id have to say its a tie between Mike Portnoy and Danny Carey. As far as solo playing comes, i enjoy listening to Thomas Lang or Tony Royster Jr.
Neil Peart still has a special place in my heart, but he finally got knocked down to number 2. Steve is just something else in my opinion. I think he is the most well rounded drummer out there, and a great educator. His techniques are fantastic, he can do anything at all that he wants with the time when he's playing, be it straight grooves or polyrhythmic soloing, and he works drumming from other cultures like East Indian into his playing as well. And also when it comes to the history of drumming and knowing where everything he does came from, he really knows his shit.
And Vital Information is just such a great band.
My other top faves are Danny Carey, Buddy Rich, and George Kollias, but there are sooo many others out there that are just superb.
I find thse kinds of questions hard to answer. Probably because I like so many drummers. Gadd is probably the ultimate drummer today. He is so musical and so great at performing exactly what the song requires. While adding his own personality at the same time. But having said that there are loads of others. I always admire what Steve Jordan plays. Michael White is another who never puts a foot wrong. Abe Laboriel jnr is another. Harvey Mason is yet another. I don't know if Earl Palmer has retired, but I always thought he was amazing. Jim Keltner. God, the list is huge.
