I have been really heartened by how much coverage there has been about inequality of pay across the board, between the entertainment industry and almost every industry worldwide. And just the problem of young women not getting an education, not being able to have an equal position in the cultures all around the world.

A lot of political music to me can be rather pedantic and corny, and when it's done right - like Bruce Springsteen or Jackson Browne or great satire from Randy Newman, there's nothing better.

We did a two month tour with Taj Mahal that was really healing and cathartic and a good distraction after my brother passed away. Then I knew I wanted to take a year off, and it was really nice to have that chance to fall apart.

Sometimes I'm more true when I'm up onstage than I'm able to be in my regular life. It's not as exciting to be at home, but I've got to learn how to make that work, and then I will be an ordinary woman.

I don't go into any album with a concept or a deliberate direction. It's more letting the best music that really appeals to me at the time, the best songs that I find after many months and years of search and sifting through my collection, and asking radio people and journalists. It's really an ongoing search that's as much daunting as it is somewhat exciting.

The consolidation of the music business has made it difficult to encourage styles like the blues, all of which deserve to be celebrated as part of our most treasured national resources.

I think people must wonder how a white girl like me became a blues guitarist. The truth is, I never intended to do this for a living.
