There's the tradition in jazz of having the “Battle of the Bands” and you do not want to get your head cut when you're playing.

Many a revolution started with the actions of a few. Only 56 men signed the Declaration of Independence. A few hanging together can lead a nation to change.

Jazz music is America's past and its potential, summed up and sanctified and accessible to anybody who learns to listen to, feel, and understand it. The music can connect us to our earlier selves and to our better selves-to-come. It can remind us of where we fit on the time line of human achievement, an ultimate value of art.

Nothing else will ever capture the democratic process in sound as perfectly as Jazz.

Many heroic things happened during slavery. And remember that there was a national movement away from it even at the time. The era of Reconstruction and then the subsequent dismantling of Reconstruction sent us in a tailspin. Then we had the Civil Rights movement. Now we have our first non-white president. We have a pattern of moving apart and then coming back together throughout the history of this country. Each time, we come closer.
