Great playing... He states he made a sequence first (B&D), then played the piano part over that.
I honestly think that making ourselves constantly input the chords with the LH, and restrict ourselves
to a RH solo only (or comp in a less than sparse way, because of the necessity to have the chord
recognition be clear about our intentions) get in the way of good jazz playing. Comping isn't playing the
damn changes on the 'one' all the time. But you had BETTER do that if you want the accompaniment to
follow the changes well.
This two stage approach is FAR more musical, IMO. Create the backing first with the arranger, strip it
down to as little as you can get away with, then play your solo knowing that you can ghost for a while and
things won't fall apart...
You lose a little flexibility in changing the chords willy nilly on the fly (but nothing stops you from doing that
while you prepare the sequence), but gain back the ability to take it outside or ultra minimal without
freaking out the chord recognition. And, don't forget, with a Mark.Jump enabled arranger, you can still
prepare up different sections or different alternate chord sections, and switch to them on the fly. I
honestly think that his system of sequence first, solo later allows the more realistic live playing...
