I never practice my guitar. From time to time I just open the case and throw in a piece of raw meat.
Regardless of what you play, the biggest thing is keeping the feel going.
To me, the guitar cuts through. It carries more than the organ, but the organ has got more guts.
When I got pretty good I went on the road with a group. We starved.
If a jazz player is really playing, the classical player will have to respect him.
