Best rock bass player

So many great ones mentioned....I second (or third or fourth) Lesh, Entwistle and Graham Maby (so glad he is getting props here--his work with JJ is amazing! Geddy Lee (don't like Rush but his skills cannot be disputed) and Dee Murray--yep! Did anyone mention John Paul Jones? What about Leland Sklar and all the studio work he has done--awesome bass guitarist!

Rob Wasserman, a true artist on the bass, but not yet mentioned. And Led Zep would not have been one of the best rock bands of all time without John Paul Jones. First four Allman Brothers Band albums allowed Berry Oakley to show his wonderful talents (c'mon, the intro to Whipping Post is one of rock's best ever bass lines) and let's not forget Adam Clayton of U2.

Does Wasserman play electric? I know he's a fine upright player. How about Jim Fielder (Blood, Sweat and Tears, in their heyday, also appears on Freak Out and Buffalo Springfield Again)...

Yup .... Wasserman plays electric. A really cool electric upright and a more "traditional" electric bass guitar. Listen to his "Duets" and "Trios" albums for some excellent tunes.

Wasserman plays on a great Rock/Jazz (as opposed to Jazz/Rock!;) record; 'Cosmic Farm' and totally kills it! The record has a 'fat' & 'beefy' bass sound!
