I had Wooten in mind, but I wanted to leave fusion bassists outta this one, even though I included some fusion players in my guitarist list. He might have some rock stuff I haven't heard but that's probably a small portion of his work, he's mostly known for his jazz work and his work with The Fleckstones, who I don't think really count as a rock band.
But I knew he would come up, as well as guys like Jaco and Stanley Clarke. Not an oversight, I just think fusion wouldn't really fit in here, it's too hard to compare bassists like that to Jamerson and Entwistle. Bassists serve a different role in that kinda music, it's more solo oriented. Plus fusion bassists would make up a good portion of the list and not everyone considers fusion rock.
Martinie is a controversial one, he's a very talented bassist, he's just in a band no one likes, but I have the guy from Korn and Martinie way is better than him, so on second thought I might need to add him to the list.
I spent like a week working on this, though the lower spots are obviously a bit rushed and desperate. I had Rex Brown in there at one point.
