We're re-issuing one of Duke's most popular lessons with new sheet music, re-mastered video and updated loop points. From Duke:

Hello Folks, this month we are going to dissect Jay McShann's "Jumpin' Blues" which I recorded with Scott Hamilton in 1986 for an album entitled "Swing".  We start as always with the chords. This type of swing blues has more chords than the normal 12 bar and the chords for certain verses are arranged while some are more open as you follow the soloist. We learn the first chorus playing in a sort of Freddy Green style we chords descending for the first 4 bars following the bass line.
