Culture dictated from above is the enemy of folk music. Whether it's stuffy classical music or pre-engineered pop where somebody's paid tons of money to make sure that everyone hears this song a certain number of times a day - that feels like the opposite of folk music.

I think that anything is a form of folk music. That's just me being glib, but the thing I like the best about humans, and there are not many other things besides this, is that humans make culture. If you're an artist, a big part of folk is noticing what other people are doing and incorporating it and changing it - the way that songs warp and change over time.

If I'm working on a set of songs, and thinking about putting them together in a collection, I start to think about what they have in common. Either on purpose or without meaning to, I shape them all in the same kind of way, because I'd rather the album feel like a galaxy of things that all have to do with each other. I do that with sonic elements, too - it's a matter of each record having its own specific identity.

When you're a songwriter, people wonder about your personal life and the meanings behind the songs, and that can feel pretty invasive, so you become protective about your inner world.

If you were a performer that only had an acoustic instrument, back in the day you couldn't hide behind your guitar pedals or the production or the vibe. There was performance and then there was the song, and that was all that you had.

Everybody has had the experience of something they love - whether it's a pop song or a painting or a movie - feeling so perfect to them that it's almost like it came from another planet. It has nothing to do with ordinary life, which is very plain. And there's something depressing about that in a way, because you feel like you're this small little human, and you feel like it has nothing to do with you.

There is a definite difference between live shows and the recordings. The recordings are for all time, hopefully, so you do want to bring across layers of subtlety. But the live show is this primal experience that everybody's having at the same time, that the recording can at best try to imitate or duplicate.
