Watch the RJ Classic online guitar lesson by Jeff McErlain from Solo Factory: Chicago Blues
RJ Classic is the quintessential blues turn around. You can hear this turnaround on almost all of the Robert Johnson recordings. I am sure you know about Johnson but if you're not familiar with his music I highly recommend you pick up "Robert Johnson: King of the Delta Blues Singers". Johnson only recorded 29 songs in total in the 1930's before his death at age 27. The story of him selling his soul the devil at the crossroads should never out shadow his contribution to the blues of which he was a true master. Like BB King, Albert KIng, Muddy Waters, Jimi Hendrix, and others, he was the real deal.
