Should not John Paul Jones be considered among the rock bassists? Also, the work of Rick Danko with The BAnd is truly memorable if you considered the complexity of his playing given the fact that he was singing much of the time.
Among all genres, there have to be other options. James Jamerson with Motown is one. IN the jazz world, there is Ron Carter among other giants. Larry Brown created funk.
Nah, I can't vote in this one....
