A quick followup: I’m pretty well versed in ‘modern’ jazz harmony including tritone subs and backdoor dominants and Barry Harris etc, and I cannot find any path there to explain the first four chords of the second half of the guitar solo. Starting at the end, they resolve to E major. Major chords as a resolution are common of course. But C minor > D major > Bb major? With no 13ths, 11ths, 9ths or even 7ths? No stacked fourths? Just plain ol’ triads? With tension ratcheting sky high all through, and then clearly resolving on E major? Since when is Bb Major a tension chord? Even the mystical Coltrane circle offers no help. This truly is genius harmony.
