It constantly changes...and I don't really have a "list" of favorites because that would make me feel obligated to that list...and I'm always changing my mind about what I want to hear...BUT...
I have always loved Buddy Rich. He was probably the first drummer who I was aware of because it was always a big deal in my house when he was guest star on The Tonight Show with Johnny Carson or one of the other contemporary talk shows.
When I was a little older, my tastes were let's say....um...stupid...so I won't go into those names! lol! However, having said that, I was always a Led Zeppelin fan and loved that big fat powerful Bonham sound. It kinda defined the sound of that era, in my opinion. A bit beyond that, Carl Palmer...then a little later, Alex Van Halen (mainly because of VH's first album)
When I started to really understand what could be done with a drum set, I was listening to a lot of jazz fusion (I hate that term!) bands. And of those bands, a few drummers stood out for me...
Billy Cobham
Steve Gadd
Peter Erskine
And lately, I've been listening to all kind of drummers...
Jon Falt, Jon Christensen, Eric Harland, Dafnis Prieto, "El Negro", Keith Carlock.....TONS of players! I can't even name them all.
