Because the blues is the basis of most American music in the 20th century. It's a 12-bar form that's played by jazz, bluegrass and country musicians. It has a rhythmic vocabulary that's been used by rock n' roll. It's related to spirituals, and even the American fiddle tradition.

The blues is always there. It's going to be hard out here, but it's all right. It's all right, and that's what the blues teaches you. You got to roll with the punches and find your equilibrium.

What takes its place is very dry education. And the tools that actually can teach you - singing and playing, learning how to participate with other people, spiritual richness - are replaced with a big emphasis on how to memorize things. That's such an incomplete education. Survival of the fittest used to mean being bigger and stronger.

And that's the soulful thing about playing: you offer something to somebody. You don't know if they'll like it, but you offer it.

My older brother and myself always played together in bands, but we never knew we would be professional musicians.

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.

When did we begin to lose faith in our ability to effect change?
