If you're stuck in a situation that's painful or there's something that makes you angry, it can enable you to step back from your own experience of it and realize that this is just a part of what it is to be human. It can allow you to accept it a little bit more and make you feel like it's less unfair.

The interests behind fracking are very powerful and they've managed to control the dialogue for a while, because they have forced people to sign disclosure agreements; people who have had negative experiences who are not able to speak out because they've signed disclosure agreements with the gas companies. Things like this. They've managed to strangle the opposing viewpoint, but it does seem like the people who are against fracking have started to gain some traction and the realities of what an environmental nightmare it is are starting to become known.

I make myself suffer with a lot of self doubt.

With me, it's so eclectic and all over the map that no one knows what to expect, ... It may not be a great career move, but all these things - singing with the Funk Brothers and the Dead, singing a Dolly Parton song - is great. I'm welcome to all these different worlds, and that's been wonderful.

I think I had a tendency to get stuck inside my head and go to some very dark places in my mind, and get stuck there. I couldn't see a way to get out.

I have to say what I do is not easy and there are definitely moments where I feel inadequate to the tasks I've set for myself. And that's hard to feel - like you're giving your life to something and you can't really do it as well as you want to do it.

If you listen to soul music, or R&B music, or Blues music, a lot of that came from church music and spiritual music, and music has always been a really really powerful tool that people have used to get them closer to God - whatever they define God as. And for me that's always been part of what drew me to it and keeps me coming back for more.
