Gary, no, that is all arranger... Pianostyle mode, Bass inversion on. You can see him holding the root with the LH, and then it's simply good technique on the solos. See him go from Var1 to Var2 (with the fill) at 0:35?

The only thing going on in the ACC is bass, drums and that background organ comping, the primary comping coming from his playing rather than the machine.

This, with jazz, to be frank is the way to do it. The less ACC you have, the more important what YOU play is, and the more you can vary it and make it your own. The minute you rely on enough machine to be really noticeable, that's the minute you start to realize it's a machine!

Those exact same chops (although he might go to more rootless chords) would work in a live band situation. I'd be surprised if this guy plays primarily with machines... What a waste if he did!
