Quite frankly, I've always listened to the black side of the radio dial. Where I grew up, there was a lot of it and there was a lot of live music around.
I'm not a jazz singer.
As far as other instrumentalists, I used to love mellow sax players like Paul Desmond. I love piano.
The short answer is, yes, I think I have become a better singer.
I was a guitar player first off.
I love all kinds of music.
