Apart from what you mentioned, I'd have to say Jim Black, definitely one of my favourites - check out Dave Douglas' Tiny Bell Trio, Peter Epstein's Quartet, Pachora or his own band AlasNoAxis...
He asked me which essential drummers he should check out.
I think it's been discussed in the past, but I'm sure in the meantime some of you have got some new input/ ideas.
Of course I recommended some of the guys I admire: Tony Williams, Joey Baron, Elvin Jones, Boris Williams (ex The Cure), Mike Portnoy (Dream Theater), Terry Bozzio (btw: check out some of his mental solo videos here: http://www.vicfirth.com/artists/bozzio/mediaframe.html ); and some people I have heard you talk about like Hamid Drake and Susie Ibarra.
Any more ideas? (Looking forward to your replies, since they are always helpful and interesting!)
