This is where you lose me.
Ask the under 40s or maybe even the under 45s and far more of them will know who Joe Dart is than Tony Levin.
To bass players aged 50+ Levin is one of those legendary old pros like Sklar, Flowers, Kaye, Jamerson, Dunn and so on. But do non-bassists know or care who they are? Not so much. Does the bloke in the street who loved the Sledgehammer video have a clue who was on it other than Peter Gabriel? No.
Did Levin ever get a sold out crowd at the MSG actually singing along to a bass instrumental? No. He's just not visible enough.
JD is very visible in Vulfpeck and Stratton regularly calls him forward, makes him the main point of interest for various tunes. That's how the muggles know him as much as the bassists do.
Legendary status for musicians has always been about visibility more than ability.
