As a guitar player, you can gravitate to the blues because you can play it easily. It's not a style that's difficult to pick up. It's purely emotive and dead easy to get a start with.
From the time I moved to San Francisco in 1967 to play with the Steve Miller Band, there was a lot of support in the music community for one cause or another, but this one was special because it was put on by people who understood where musicians' hearts are.
I felt that, in retrospect, there was a time in the late Seventies, after I had a string of hits and successes, as a performer and a recording artist, that I wasn't saying anything.
I listened to classical guitar and Spanish guitar, as well as jazz guitar players, rock and roll and blues. All of it. I did the same thing with my voice.
I'm still trying to re-create a Ray Charles concert that I heard when I was fifteen years old, and all my nerve endings were fried and transformed, and electricity shot through me.
