Okay this one is not for one of the all time greats, but is worth checking out. On his latest CD, "The Last DJ", Tom Petty handles bass playing on about 2/3 of the disc. They were between bass players when they began recording so TP stepped in. He was originally a bass player in his pre-Heartbreakers band, Mudcrutch. The liner notes indicate who plays on which song. TP's playing is really first rate: solid and very inventive. The two tracks that Ron Blair (the original and recently returned bassist of the Heartbreakers) plays on are cool, too. (Check out the outro on the albums final cut, Ron really lets loose.)
