I think Bud was always "really" Bud, depending on where Bud was at at any given moment...
I don't hear "dire" or "chains" here, I just hear Bud when not all the synapses were totally connected, but the ideas were still coming, and he made them go through with what he had. It's nothing like when he was "firing on all cylinders", but there's some harmonic turns in there (in both right and left hands) that he connects so unblinkingly that it makes me smile anyway. Working with less available maybe, but hardly chained. Whatever "space" he was in, he was in it.
and this, so right within itself (and again, that left hand, some of those choices...they work, he knows why to play them, because he knows where he's going with them, whatever "issues" there are are not of a lack of ideas or inspiration, and by god, whatever physical/mental connection issues he might have been having, again - he found a way to get it out and make it fit).
