I worry more about the marketing that's taken hold since the 70s. The Jazz era, the Swing era, those were huge. Entire decades were named for music. In the 1940s - after World War II - changes in taxation, ballrooms closing, people moving to the suburbs, and the onset of target marketing and the confusion of commerce with art caused some things to happen as a result that have taken us away from jazz and what jazz offers us.

The blues. It runs through all American music. Somebody bending the note. The other is the two-beat groove. It's in New Orleans music, it's in jazz, it's in country music, it's in gospel.

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.

It's harder to build than destroy. To build is to engage and change. In jazz, we call progressing harmonies changes. Changes are like obstacles on a speed course. They demand your attention and require you to be present. They are coming...they are here..... and then they are gone. It's how life comes. Each moment is a procession from the future into the past and the sweet spot is always the present. Live in that sweet spot. Be present.

As you get older - for example, in our band we have members of our orchestra, like Carlos Enriquez and Ali Jackson and Walter Blanning. I taught them when they were in high school, and now they teach me.I'll regularly call Ali and say, "Man, can you break this rhythm down for me?" Or Carlos was actually our music director in Cuba, and he's been instrumental in a lot of my education, and I started to develop a saying with them, because they tease me all the time - you get older, you have that familiar relationship - I say, "You have to follow your young leadership, too."

Jazz celebrates older generations and not just the youth movement. When you "sell" only to people of a certain age, you get cut off from the main body of experience. The power of couple dancing and courtship, it's elegant, and you wouldn't realize America was once a nation of dancers and singers today. People of all races could dance and sing.

Blues is like the roux in a gumbo. People ask me if jazz always has the blues in it. I say, if it sounds good it does.
