Chest Pounding Bass!
Dont know if we already have/had one of these threads (nothing came up on search?) but how about the Lowly BASS.
As always the bass player rarely gets much attention and without them the Groove just wouldnt sound the same.

Lets not limit it to Rock for Jazz has had some great talent as well -
and besides...We All Love Really Good Bass!

I'll start, one of my favorites has always been Stanley Clarke (kind of obvious but what the hey!) more of a jazz fusion thing but his early stuff is really amazing. Has featured a lot of great guitar players to complement his style...Jeff Beck, Bill Connors and John McLaughlin to name a few. His more recent stuff is a little tame, his 70's stuff is the ticket
