I was totally into jazz in my teens.
I don't like playing standards. I like to do my own cutting edge work.
Of course the playing is important but writing and the establishing of what you are going for is prime too.
What I wanted to do was play the guitar but I don't like instrumental rock. I think it is tripe.
I think rock records tend to be very expensive.
You're on the stage and you've got all those people yelling at you, so you better be right in the moment, reacting to that. It's completely live and organic. Even 20 years later, it's the same thing. You may be even better on your instrument. Hopefully, you are.
