Man, you need to listen to the right Jaco recordings. One of the most swinging and funkiest players ever. Different than Paul Jackson, both super great.
Hancock's 4 A.M., Jaco + Mike Clarke, one of the most amazing tracks ever. Try to play a groove like that, never one bar the same but always always in the groove. Listen to the 1st bar of Herbie's solo, that pickup (or absence of) is unbeatable.
regardless of recording, jaco was always pushing the beat and playing notes all over the place. now, imo, its not the busyness that made it not very funky because rocco and p.j. were playing pretty busy too, but it was less notes.
i like chester thompson's description of jaco
Thompson described it to World Of Genesis webmaster David Negrin: "Jaco was very much wanting to be in the band. So, he was pretty much being the Yes Man to whatever they said (laughs). The [Black Market] rehearsals were a bit strange, because the songs that I had just recorded with Alphonso (Johnson) playing bass were 180 degrees different with Jaco (playing bass). Alphonso had this wonderful sense of space when he played, and Jaco was just all notes. It just didnt work. I suppose, I certainly could have made the adjustment, musically, but to be honest, I really didn't care to."
I would think that James Jamerson would get quite a few votes for that title. Am I wrong?
