Name 3 under appreciated pop/rock drummers

Can't think of three but tend to agree with Ryriken. I don't think Ringo gets the respect he deserves as drummer in the Beatles. Maybe because he wasn't so much a straight ahead rock drummer but (to my mind) more a percussionist/accompanist. (And "yes", I'm aware that on some tracks, McCartney played drums).

I'm not sure anybody who knows rock and roll would consider Keith Moon an under appreciated drummer.

Crazy as a loon but a great drummer.

Ginger Baker
Michael Shrieve
Tony Williams (jazz)

The vast majority of the people mentioned above were very well-appreciatated in their day - Dino Danelli, Jim Gordon and Jeff Porcaro, in particular, were some of the most highly-regarded players of their time. I will vote for Graham Lear, who I saw with Santana. Incredibly good player. Also - Clive Bunker, who played like a cross between Keith Moon and John Bonham, IMO. Check out Tull's You Tube video on My Sunday Feeling for a good example of his playing. BTW, Ian Anderson's outfit in that video is absolutely the most outrageous/ridiculous thing I've ever seen. And I've seen quite a bit. Tights, knee-high boots and a bathrobe thrown over the whole thing. Yet, it made sense back in '69 or so.
