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.

You don't have to look a certain way to have a hit record.

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.

Elvis might have compromised his musical style a bit towards the end, but that doesn't mean that artists from the rock n' roll/folk-roots culture - of which he was not really a part - shouldn't get better as they get older, like the great jazz or blues artists.

I'm sure I would have been considered a more significant artist if I was a singer-songwriter. It's just not the way I roll. I love being a curator and a musicologist. People write me letters and thank me for turning them on to Fred McDowell and Sippie Wallace, and that's partly my job this time around.

I don't want to sound like a self-help book, but it really has been transformative for me to take a look at my relationships in a new way and see my part in them. Everybody's going through that.

The great thing about the arts, and especially popular music, is that it really does cut across genres and races and classes.
