Some of those guys you mentioned are relatively high in influence....some perhaps not so much. A few others from other genres...true, some fusion and not solid rock...tough to rank for this list...(Marcus Miller as perhaps the most obvious). I also look at Ready Freddie who is influencing an entire generation of younger bassists on the L.A. scene, plus those who have gotten turned onto him through his Steely Dan live performances (end of Ready Freddie rant). Of those you mentioned, I'd rank Watt, Levin, Hamm, Burton (which includes Claypool), Choy, and Harris ehh, influential (of those I'm real familiar with)...and the rest of the chorus will chime in and throw Flea into that mix...even at the top in the opinion of some.
Your point about Freddie is well taken, and thanks for reminding me about his hiring as the bassist for Dan - an EXTREMELY prestigious appointment that speaks very highly of him and will influence his ultimate placement on this list.
Will Lee is another one of those guys with strong rock credentials, but also a huge rep in other genres and situations. Skill and creativity to the max though.
I believe it. Looking forward to doing some intensive youtube listening :-)
Phil Chen is rock personified...right from THE era. His work with Rod Stewart and Jeff Beck especially was as solid as a rock. He is a Jamerson devotee, and mixed Jamersons style with British rock, and while many of the Brits did that to some extent...Chen was a bit more dedicated than most to the integrity of that Jamerson philosophy on bass.
So I'd say that Lee and Chen could hover in the 30's somewhere. MFSB's Ronnie Baker a possible upward move???
Good point on Chen, playing with Stewart & especially Beck in the 70s is definitely significant.
Baker is maybe the most obvious upward move on this list. He'll almost certainly make top 50, I wouldn't completely rule out top 40.
