Asked my SO what she thought about the performance without saying anything to her about the bass. Her comment: “It’s ok. Nice vocals. But it doesn’t make me want to get up and dance. Something feels off with it.”
See what I mean?
As for overplaying, uh, have you guys never listened to Jamerson? At the time he recorded this stuff you guys would have been SCREAMING that he was overplaying and a REAL bass player would never dare to play so many notes.
James Jamerson wrote the book, and as often happens with the supremely talented put at the right place at the right time, HE could do it and make it work. The rest of us mere mortals are shooting horse in the driveway wishing we were Michael Jordan.
Jamerson at work, with Benny Benjamin on drums along with the rest of The Funk Brothers, on my favorite version of 'Heard It Through the Grapevine' from 1967, and him and his one-finger picking are ALL up and down all over this, and he . . . never . . . puts . . . a . . . foot . . . wrong.
And you're right: Me, I'd sound way to busy trying to emulate the divine, but not him, not in this context, not on this chart, not with these other musicians, and that prodigious talent in this setting just works, all day, every day.
