I think I might chip in on this one... Stuart Zender was always my favourite player and Paul Turner, the new guy with Jamiroquai has an amazing feel and groove. Other notables for me would be Randy Hope Taylor, Dave Holland, Andy Rourke, Colin Greenwood for his remarkable ability to keep it simple and moving, Yolanda Charles, and particularly (most importantly) Pino Palladino.
In regards to Dave Holland, he taught one of my lecturers upright for a while, who then went on to play with Mike Walker on a lot of gigs... Mike and Steve are both remarkable musicians, and have said they owe a lot to him.
