I think that my sensitivity to music has actually deepened and expanded as I've gotten older. You add more life experience.

My dad [Johnny Cash] went to the [Richard] Nixon White House and refused to sing "Welfare Cadillac" (instead performing the anti-war songs "The Ballad of Ira Hayes" and "Man in Black"). He protested the Vietnam War, but he went to perform for the troops with bombs dropping all around him. He had that kind of genius: a true artist's capacity for holding two opposing thoughts at once while being large enough to encompass all realities.

Isn't that the goal, as you grow older? That you start reclaiming those parts of yourself you didn't recognize or didn't think were there all along? That's what happened when I made The River and the Thread record.

I love mixing up my genres.

I gave up language for a while, and I started painting.And then I only listened to Miles Davis and other instrumental music to see how it felt to be without words.

My dad and I had a real meeting of the minds. We loved to talk about music, politics, and art. He loved children. The thing I missed most about my dad when he died was that this person who really gets who I am at the core was gone.

I found it was really impossible for me to write songs when I couldn't sing.
