I'm a songwriter. My voice just serves what I'm writing about. So to let all that go, I mean, bring the sensibilities of it actually to the song choices, but to just be the interpreter was incredibly liberating and really fun.

Southern gentility is evocative to me.

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.

Celtic music is part of the language in Scotland and Ireland, where every kid and grandparent knows those songs, music by the likes of Woody Guthrie and Hank Snow is getting entrenched here. They are part of our cultural language. It's part of a living treasure. It doesn't just belong to a museum.

I choose not to give energy to the emotions of revenge, hatred or the desire to subjugate.

I couldn't listen to music with lyrics for the first few months after the brain surgery, because they were too complex and disturbing. So I listened to a lot of classical music. I didn't really want to read, either, so I listened to books on tape or watched movies. I also re-taught myself all of my childhood piano pieces. It helped me repair my brain.

The thing that scares me most is the shift from serving the people to exercising power and with it, this attendant narcissism. Sarah Palin is a great example of someone that just stirs the pot for the sake of the attention.
