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 kept saying I got sick of listening to people's productions, like people who had no ideas, no songs, nothing to say but could still con people's ears into thinking those songs were there by the application of production. I kind of wanted my record a little more honest than that: "Well, this is us. We put a microphone on it. Here it is."

Sometimes it's easier to make decisions when you know that you've tried things that are so wrong, you know, "OK, I don't go that way with it. I don't go this way with it." The way I work, I kind of have to go down all those wrong paths to know that the one I'm doing really is the one that is going to work.

I want my records to be the most magnificent and glorious-sounding records, but also want them to be the most intense and fragile. And I want that all in the same ten-second bit of music. And it just takes a while to get there, and I don't write the songs and then go and record them, I write in the studio. So it takes a while to kind of piece them together and know that that's what I want it to be like. And I constantly throw the bits up in the air and see how they land, and eventually they kind of keep landing in the same place and that's where it stays.

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.

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.
