Leaving aside personal preference and whether you like JP and/or Dave Weckl, I have to say I'm slightly baffled. That some posters, note I say some, can lay down "definitive" judgements on tone and timing based on a pretty cruddy Youtube copy with obvious sound quality and possible synching deficiencies. That allied to the probably sub optimal playback systems attached to most PCs make for an exercise in futility IMO.

Video being out of sync does not change the 'groove'. How is that even possible? Turn your screen off and just listen to the sound. It bears no resemblance to Jamerson style. After listening, search for jamerson groove and take a listen. It's still unmistakable Jamerson, even on crappy sound quality.
