This is a good introduction for blues pickers to break outside of the 12 bar form. So many great players played Rhy. Changes and somehow it’s no longer a popular form in Blues today. I know when I heard Little Charlie years ago play this progression I was totally consumed. More so I wanted it to sound like vintage Swing not modern jazz. Unfortunately my guitar teachers years ago wanted to show me a harmonically complex variation. Definitely not the Charlie Christian or Les Paul sound I was looking for. This video is great way to get your feet wet.
