I'm not a jazz singer.
I'm easily distracted by other things in the world around me.
The short answer is, yes, I think I have become a better singer.
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.
A lot of what I have always done is do other singers.
I think that it can be said of a lot of artists, and myself included, that we made the same record over and over from the beginning.
