I'm not that beautiful, and I don't want to be a pop star.

I'm glad people think I'm a badass. I'm a rock and roller, and I'm an R&B and a blueswoman. I don't do fairy music, although I love Celtic music and sensitive music. There's a balance between ballads and kick-ass songs.

I'm honored when young people say they've gone to school on slide guitar with my records. But people get their influence from my live shows and records and YouTube, not me personally. I walk around with a hat on. People don't know it's me.

I thought I had to live that partying lifestyle in order to be authentic, but in fact if you keep it up too long, all you're going to be is sloppy or dead.

One of the biggest obstacles I've overcome in my life was thinking I didn't deserve to be successful. Artistically I'm not as much of a heavyweight as someone like Paul Simon or Joni Mitchell, because I'm not a creator of original music, and I worried about that for years.

Quakers are known for wanting to give back. Ban the bomb and the civil rights movement and the native American struggle for justice - those things were very, very front-burner in my childhood, as were the ideas of working for peace and if you have more than you need, then you share it with people who don't.

I grew up in Los Angeles in a Quaker family, and for me being Quaker was a political calling rather than a religious one.
