I used to listen to so much doo-wop, and I've talked a lot about gospel music, but I realised a lot of that language came from doo-wop music. You know, "I Asked the Lord Above," "Heaven Sent Me an Angel." That's rock-'n-roll, and that's where a lot of this language is coming from. Also, I've said before that as soon as you start having a conversation with Jesus in a song you know you're dealing with issues of morality and how fragile it is to be human. It's a shortcut to putting those ideas across.

I just think there's an awful part of rock-'n-roll music where people kind of pretend they're young all their lives, you know? And they kind of live off past glories. Especially now there's kind of a trend where people are performing only their old albums, in their entirety, beginning to end.

When it's a pop song, I don't really want to do pop songs, but they exist and sort of come out by accident.

I'm obsessed with the science of music. I'm obsessed with the way you can string notes together and they can do something, and you play the same notes in another way and they do nothing. How the essence within songs - within words, within lyrics - finds its place.

Making a record's a real fight for me. I'm constantly fighting with this thing inside of me that says I should be sitting in a room with Matthew Shipp or I should have Han Bennink on drums or this song should be playing for the next 20 minutes in my head, not a silly little pop song. It's constant.

I've said the line about Ray Charles a million times, but nobody listens to him singing "I Can't Stop Loving You" and wonders who Ray can't stop loving. They apply that to their own lives. That will happen with my songs.

My songs get to a stage where they resist any further change, you know? And that's kind of where they are, short of re-recording or starting again. That's kind of where it's gonna be.
