I always loved Levin for his distinctive sound, and his melodic sense. He's great with Gabriel, Crim (Discipline being my fave recording of all time from anyone), and his solo work....plus multiple independent work with others. His work has done the most to inspire me to play again, this time seriously.
Not only is he a superb player but he's versatile.....and he can do it without compromising his work. And whatever he brings to the band he's with is going to be good! He's an all around artist that has done a lot to bring the bass out of the just-part-of-the-rythm-section shadow.
Plus he's a hell of a nice guy....just met him the other night with CGT and Pat Mastelloto. Real down to earth (as much as he can be for '6/something).
ALSO: Mike Watt...the man must have elastic fingers. He was the first to make playing an instrument sound like the funnest thing in the world to me.
Others:
Geddy for obvious reasons, Tina Weymouth, Chris Squire, Habib Faye (w/ Youssou N' Dour's band), whoever it is that plays in Jamiroquai.
I used to like Sting and still do back in his Police days. I can't get into his music much now.
