Watch the Twisted Soul Rhythm online guitar lesson by Oz Noy from Twisted Guitar: Blues Rhythm
Let's give a listen to "Twisted Soul". This is a really basic minor blues, going from Amin into Dmin, then from F7 into E7 and back to Amin. Stylistically, it's kind of a soul/smooth groove with a medium tempo.
We're channeling Wes Montgomery here and playing with the thumb, which gives the chords very cool voicings.
