Too many good drummers out there for me to narrow it down....but here's a list of drummers that have moved/inspired/influenced my drumming:
Dave Culross - begins and ends with this guy for me. One of the early blasters....has lightning fast feet and throws in tasty fills and jazz influences into death metal.
Alex Van Halen - THE reason I started playing drums in the first place. I can't hear a song off '1984' and not want to immediately jump on my kit.
Kevin Talley - the guy's kinda of a whore jumping from band to band....but holy shit can this guy play. I've had the pleasure of seeing him play with Dying Fetus, Suffocation & Misery Index live and was utterly shocked each time.
Stewart Copeland - his hi-hat work and wet snare sound are absoutely tasty. 'Spirits in the Material World' has easily one of the best snare sounds ever.
Steve Asheim - waaaaaaay underrated. Nothing terribly flashy but this guy is borderline autistic-savant with some of his chops.
