My first love was the sound of guitar.
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.
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 was a guitar player first off.
And if it's not there - if that little melody is not in my head, or if I just don't really feel like picking up the guitar - I just don't do it.
