It depends on the project. I’m working on a novel now, which started by taking a weird interest in something and circling around it. I think in the early stages, I like to do a lot of really rough draft brainstorming, trying to generate a lot of words, even though I know they’re not going to be part of the final draft. I find first drafts challenging and, actually, I prefer the revision stage, because it seems so daunting to create something out of nothing.

We started at Caltech asking very simple questions: how do we understand the molecule dynamics or the dynamics of molecules, emotions and so on, molecules but in a coherent fashion.

One of the things I worked on with this album was focusing on the lyrics and the melody more so than everything else. A lot of my songs have started with the music and the texture, and then the lyrics and melodies are all framed inside of that. I wanted to do the opposite with this one and have melodies that could stand on their own without the instrumentation. I wanted it to sound just as natural if you were walking in the woods, whistling them as they do with accompaniment. A lot of these songs started with melodies that I would hum into my phone while I was walking somewhere. “Dancing in the Club” and “All Fucked Up” were both written that way.

In my early twenties I wrote quite a lot of a very bad novel called The Private Joke. I regularly abandoned it for months at a time to write other things, then picked it up again. Part of the manuscript was sitting up in the luggage rack when, aged 25, I was travelling by train from Manchester to London, and the idea for a very different kind of book hit me: that of a boy who didn’t realise he was a wizard, and was taken off to magic school.

Well, if I had studied theater, I would not be making the kind of theater that I’m making. My theater came about by living. My first play that had text was written with another 13-year-old young man named Christopher Knowles who spent 11 years of his life in an institution for brain damaged children and was composing text that were arranged mathematically and had to do with geometry. I was fascinated by his mind and the way he was putting words together. Not only was it interesting to hear, but it was also very interesting to see. It wouldn’t be necessarily right for someone else, but for me it was something I was drawn to. It came about by living, not by reading a book.
