Then I came up with this crazy idea just to walk out on the stage with no band at all and just start singing whatever came to mind. I actually fought the idea for a while because it seemed almost too radical, but it became obvious what I was supposed to be doing.

Improvisation means coming to the situation without rigid expectations or preconceptions. The key to improvisation is motion — you keep going forward, fearful or not, living from moment to moment. That’s how life is.

I bury my mind in my book, the Bible. Every morning it's the first thing that I do. I've been doing it for years and years. So I want to come back here [to Israel] to see the places that I read about every day. It's very important to my faith to feed [my] spirit in Israel.

I think we listen to music because we want to be changed. Music is not solely for our entertainment. Music has such tremendous power to bring joy. To me, that's our job as artists. Not happiness, not a groove, whatever. You must bring joy. I think that's the assignment. I have no doubt about it.

When we listen to improvisational jazz, or solo classical violinists, the way they phrase and inflect melodies feels vocal, like they’re talking to us. When I was figuring out how to perform solo, I wanted to move back and forth between bass riffs, melody, and harmony, so I often used sounds instead of — or alongside — the words of a song. I found that if I sang a line using the consonants, vowels, shadings, and inflection we recognize as human language sounds, people responded as if I were talking to them.

Miles Davis turned his back to the audience when he came out on stage, and he offended people. But, he wasn't there to entertain; he was all about the music. I kind of do that.

Music is still part of my spiritual life. Sometimes I sing my prayers. When I get audiences singing, I hope I'm helping them feel connected to something beyond themselves.
