I listen to music all the time, and I just choose things I like, or things that I've not used before. Sometimes I work with music that's very difficult - that I don't even particularly like, per se, but that is really complex or interesting.

Everyone is always telling me that I must be exhausted, but I've learned how to use my time well, and that includes holidays to recharge. I always try to give myself big chunks of time to think about what the next project is going to be.

Misbehave more beautifully; more often.

I heard Joby Talbot's Hovercraft piece for orchestra and felt its immediate physical impact - visceral, unsettling, hungry and direct. These short five minutes became our keystone to unlocking a strangely seductive score that tensions the aggressive force of the White Stripes with the enigmatic beauty of Talbot's own compositions.

I think it's the responsibility of a major opera house not only to cultivate debate and get people thinking, but also to be interfaced with things that challenge them. To challenge its audience and not just deliver things that they know, even though some of those things are wonderful.

Dancers can get to see almost everything now. When I used to go into companies to make a piece, the dancers had hardly ever seen my work. Now they can watch it on YouTube. It means they're much faster at picking up material.

'Entity' is not about science. The process behind it may dictate the nature of the piece, but it's not like a dance about Einstein where I'm trying to convert his ideas into movement and communicate that to an audience.
