I can also offer some picking insights for the A blues stuff:
As per the slow motion, when he’s going between two strings it is very often outside picking. That’s his thing. So in measure 13, the 19th fret of the G is a downstroke and the next note on the B string is an upstroke. That happens in two places.
And it’s also clear he’s doing it with double escape wrist motion. I think that’s really the takeaway here, i.e. how his picking technique works. Not necessarily which notes were played with which pickstroke, per se, because that could “mean” anything. But understanding that he gets over the string by making these particular motions, and he does so with a middle finger grip and a supinated arm position. This puts him in a category that also includes Steve Morse and Albert Lee, whose techniques all function similarly.
So there is a relationship between arm position, pick grip, and picking motion. These things aren’t random. And knowing this makes it much easier to learn their techniques as well as any other principally wrist oriented technique you might experiment with.
