Victor Wooten Killer bass player. He has several solo CD's, plays with Bela Fleck and the Flecktones. There is a wealth of info on his site. Visiting his site is time very well spent.
Steve Bailey Awesome six string fretless bassist. I highly recomend checking him out. Steve has his own solo CD's. He has spent years gigging and recording with lots of heavy weight musicians.
Michael Manring A very hot bass player. He uses a lot of altered tunings and has been known to play two basses at the same time. He has several solo CD's and has been nominated for a Grammy.
Daniel McGillis A very good friend of mine as well as a hot guitarist and composer. Daniel has several solo CD's of his own compisitions ranging from pop to jazz-fusion.
