I feel like I'm getting better as a writer and as a singer and that there is more to discover there, so hopefully other people feel that way too without having to disassociate with the earlier work.

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.

Through music I've discovered other philosophies. Buddhism in particular is one that has always - whenever I've studied it and read about it, it's just been so true to me. And I do try to take some practices of that into my daily life. Whether that's meditating or trying to see the world from that perspective.

How long have you been sitting in the darkness? You forget. You know you're getting hard to be with and you're crying every time you turn around. Oh my crazy baby, try to hold on tight. Oh my crazy baby, don't put out the light. And your hands are shaking something awful as your worries crawl around inside your clothes.

We've been together so long, I hope it just wasn't the drugs.

Even if I'm doing a show and there's five people in the audience and the sound system is terrible - I mean, it's been a while but I've certainly done those kind of shows where it's just every conceivable thing is against you - you still have music. It's still something that's real whether there's five people in the audience or a hundred thousand people in the audience. And that's always been there for me.

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.
