I guess I could be singing about Superman, or about Zarathustra coming down from the mountain, but in my mind I was singing about Julian Assange. I wish I could say that Nietzsche inspired my lyrics but all I can honestly say is I was inspired by the graphic design of these '70s paperback covers for Beyond Good & Evil and The Birth of Tragedy and The Gay Science.

One of the nice things about being in a band is that you depend on each other for ideas, so it's not all up to me to do everything myself. There's always that fear that you'll run out of stuff. The most difficult part for me is writing lyrics, and that starts to get difficult after you've written, like, 120 songs.

My standards are higher than they used to be, I think. They don't necessarily have to make sense, but I certainly work on them a lot harder now -- partly because I do them on the computer, and I print them out and fix them, and print them and fix them over and over again, whereas in the early days I used to just scratch down a few things on a piece of paper.

Don't be a rock star. I've seen people around me have their lives destroyed by drugs. It just depends on what kind of person you are. Like, some people have a "go" button and a "stop" button, and some people just have the "go" button, meaning that they take drugs and just take more, and more, and more. It could be 6 in the morning and they'll say, "Okay, I have to get more now." I'm not that kind of person.

It's hard to imagine the whole punk movement without The Velvet Underground. I toured with them when they did their reunion tour, and no one sounds like that; they are a very unique-sounding band. They have a lot of noise, they have a viola, they have a drummer that's standing up, certainly they have influenced my guitar playing, but hopefully after 12 records you start to sound like yourself.

If I look at my own recordings, I think generally there is a focal point within the song and often it's the instrumental bridge or a guitar solo where we try to do something unexpected, something beautiful or weird, or beautiful because it is weird. And of course I fail half the time, but yes that is the goal, to create even a few seconds of bliss, or sadness. The electric guitar is a great instrument for doing this because it is capable of surprising you. There are so many different sounds available.

Writing a song is a long road. Or it can be.
