All the bassists that have been listed are among the greatest of all time!
There are different kinds of bassists out there... some that sit in the pocket and groove it... some that can step beside any lead guitarist and play lick for lick with them... some that slap some that pick...
Noel Redding.
Cliff Burton.... I always say that he played the 3rd guitar in Metallica since Metallica used almost no bass frequency in their early stuff and Cliff played the bass like a guitar...
Bill Sheehan... same as Cliff Burton
Les Claypool.... I mean come on!! He did the Seinfeld them music!!! haha
Pino Palladino... plays with the John Mayer Trio... guy is money in the pocket.
The dude from Dream Theater is amazing... watching him go note for note with Ruddess and Petrucci is amazing.
Roger Waters.
The dude from Tool.
Those are some of my favorites.
