Having bought the colours, an easel, and a canvas, the next step was to begin. But what a step to take! The palette gleamed with beads of colour; fair and white rose the canvas; the empty brush hung poised, heavy with destiny, irresolute in the air. My hand seemed arrested by a silent veto.

No, they are three completely different processes. In film, I try to really blank out my mind when I see the film for the first time so that I have no preconceptions. Early on in my career, I tried to do all this prep or even read the script and write music, but none of it ever survived. And I realized the best way to go at it was to be as blank as I can possibly be. When I’m writing classical music, it’s much more nerve-wracking because I’m starting with nothing! And I don’t have a picture to drive me on. I am wired now, for 38 years, that I see a moving picture, I hear music, you know what I mean? But with classical, I got nothing, and at first that was totally terrifying. But I forced myself into it, and then something develops, and it becomes very liberating. With the rock music, it’s a whole different process. I mean, I can’t do anything until I get the message.

Concepts can be really freeing in their limitations. I really enjoy when I make rules for myself in my creative practice. Whether that means I’m going to try and write a song without the use of the word “I,” I like having rules in my songs. Even if I don’t follow them exactly, it’s kind of nice to have a very loose guideline. And then when I try to create that universe for myself, I at least can visualize the path that I’m trying to follow.

We often start with the physical place itself, and with stories about that place. Deepen that research. I’m really interested in how places are constructed beyond a parochial idea of local, like what kind of stories, and what kind of movements, and what kind of trajectories are tied to a particular place. Then, once we start looking at a story of place, it somehow very often becomes a story about migration.

I wrote a little book called Screening History , in which I go in great detail into the movies that affected me growing up. This was in the years of puberty, and so on. The Prince and the Pauper , based on Mark Twain’s novel with the Mauch twins in it. All of the propaganda films I loved, because they were political.

It’s best to start writing when you wake up in the morning, or afternoon, or whenever it is you wake up. Just start then, because you are closer to the dream state than at any other time in the day, which means the imagination is really working on all cylinders, and it means that whatever it is that manufactures sentences in your head is very fresh, and you have all kinds of slants on things that by the end of the day you won’t have, or you will just lose along the way. Further advice I have not.
