ahh, how could i not post to this topic... i apologize in advance for not being able to pick just one... or ten. i'm gonna rehash some for sure, but hopefully there are some new names too. there are so many ways to judge a bass player...
Jaco gets points for reinventing the electric bass as a lead instrument while still being able to lay down a tight grove when necessary. Portrait of Tracy is hands-down my favorite bass solo/song.
John Myung of Dream Theater is straight up technical as hell, though I think he lacks a unique sound. He doubles the guitar so often that I really doubt he composes his lines.
Aside from rocking with King Crimson and Peter Gabriel, Tony Levin is probably the most prolific studio bassist alive. Just check out this list and be amazed
http://www.tonylevin.com/discography.html. I had the privilege of meeting Tony a few years ago and had him sign my copy of Beyond The Bass Clef, a great book with insight, tips and hilarious stories about playing bass. He also rocks the Chapman Stick.
John Entwistle and Paul McCartney and are two guys who really developed the art of the bass line in rock music. Of course, combine their first names and throw in a Jones and we've got a trio of bass players who found the perfect balance between function and creativity. Flea is a more recent member of that club.
When I saw a live Vic Wooten bass solo three years ago i almost shat myself. I was literaly speechless for a good hour or so. With my eyes glued to him, I still have no clue how he was creating some of those sounds.
Jim Creegan from Barenaked Ladies is great at putting subtle variations in his basslines. And he plays an upright on stage which is always cool.
The best bassist whose name I don't know is the guy who played on Zero 7's tour. He took the album's very simple basslines and made them ridiculously active with spontaneous fills and patterns without taking away from the music. I just watched him the entire show.
Bonus points to any bassist who sings. Especially in a three piece band. Sting and Geddy Lee get 7 points each. And an extra 5 to Geddy for having fifty octaves between the low range of his instrument and the high range of his voice. And for playing bass lines that have absolutely nothing to do with his vocal melodies half of the time.
Speaking of power trios, Les Claypool gets an obvious nod for creativity. A less obvious nod goes to my personal favorite bass player Robert Sledge from Ben Folds Five. Highly underrated/overlooked. A great blend of creative, non-repetitive bass lines, technical skill, unique sound and killer backing vocals. Plus, he's the only bassist I've seen unplug his instrument and "play" his patch cord.
there were a lot of guys listed that i've never really checked out like jamerson and lafaro. i'll have to get on that. sorry to be that stupid noob with the long ass post, but it's who i am
