You never know what you'll get in N.O. Once, I was at the Jazz Fair going between two venues and there were scattered "second choice" bands on just cheap platforms or kiosks between the major acts.
As we approached one such band - they were playing a burning version of the Flintstones theme - I told the girl who was with me, "Hear these guys? I've got no idea who they are, but they're absolutely world class. The music world is so unpredictable you may never hear from them . . . but world class."
After they were finished, we were talking to them and they invited us to a 02:00 jam session. They were Branford and Wynton Marsalis.
