Greatest Rock Drummers

Carter Beauford....Nobody else can do what he does.   And I've seen a lot of bands.  Palmer is pretty far up on the list as well.

BTW, seems that Audiogon should arrange for discounts with AARP now that I think about it....

Lots of great artists here, not to dismiss any; and I get it that some may
argue that Little Feat was not a rock band, but my guy is/was Richie 
Hayward; may he rest in peace. 

Ian Paice of Deep Purple, Ginger Baker for his jazz flavored rock style. Travis Barker of Blink 182. Keith Moon, although the Who said he was great playing Who songs, but could not play anything else, I love his fills and rythm .
Of course Neil Peart.

IMO to answer your question falaconquest, no he is not. There are just to many techniques/styles in drumming for one single drummer to be considered better than all the others.

And now for something completely different;

There is sizzle and there is steak...one mention of Steve Gadd, but no mentions of Bernard Purdie who can include Jeff Beck, Steely Dan, The Beatles, the Rolling Stones, etc on his resume. Spent a wonderful evening at Shanghai Jazz in NJ sitting 20 feet away from Mssr Purdie and it was one night I'll not soon forget. Honorable mention to Steve Jordan, whom we saw a month or so ago with John Mayer. Not a lead drummer like Moonie or Mitch Mitchell, but, like Ferrone, a highly nuanced percussion machine that can turn the beat inside out and back again if need be and still remain musical.
