I have always been 'aware' of Jamerson and his significant role on the electric bass but never really dug-in with his work until recently.
I transcribed 'What's Goin' On' from the studio version and was absolutely blown away at his playing on that recording. Literally, ever few seconds there's a sweet little hook in his line, a subtle pause or a tasty lick. No fancy technique, 16th notes, tap or slapping. Just flat out in your face raw finger style GROOVE. His ability to play in the pocket is simply mindblowing. The entire feel and groove of that song is all because of the bass line. It's the perfect example of the whole being greater than just the sum of the parts.
Likewise, I have a feeling the bass lines in all those other hits he played on contributed significantly to their success and appeal. It's just not obvious to the listener. Jaco has always been my bass hero but these days I'm not so sure.
great thread and absolutely deserves to be stickied!!
