Most of the clubs you see listed in the New Yorker just have duos. That's the biggest change in jazz in 15 years. The clubs where we all learned how to play were like the salons where Mozart learned how to write. They had a social purpose, we met there and listened to each other. No more salons.
Musicians can no longer afford to go to clubs.
Only tourists go, and only because they think somehow they're supposed to go. Going to a club now is like going to hear the Preservation Jazz Band in New Orleans. I have a reputation. I get students from all over the world. I like teaching, but that's not the question.
