I ain't got nothin' but the blues - Robben Ford
Played by Robben Ford and released on his album Talk To Your Daughter in 1988, the song was originally written by Duke Ellington in 1937. This sweet blues-gospel oriented ballad is in the key of Bb. The harmonic progression is amazing and pretty complex, involving many jazz cadences, altered chords and chord substitution. It's actually a very good way to improve your chords knowledge!
