The songs Levin etc have played are legendary and are well known.
That doesn't mean the fans of the songs can name the players. Certainly not for solo artists. More to the point, they don't care. They don't care if Peter Gabriel's backing band was Hendrix, Sting, Rich, and Mozart. Gabriel is the legend there, not the band members.
If legendary status was about ability then someone like Vic Wooten would be more popular than Sting. And he isn't.
Ed Sheeran -v- Andre Segovia.
Or if we are honest - any professional backing singer on earth -v- Ian Brown.
Edit. And I am talking about bass players. I think there’s a lot of under 45 bassists who won’t know who Levin is.
