Shostakovich's final pieces, his quartets, are scratching the surface of another world.

I spent the majority of time at school trying to break the rules. I would climb to the top of buildings; I even burned a building down once - not intentionally, just because I was interested in fire. I remember going through the rule book, ticking off the ones I had broken and looking for the ones I hadn't.

I allow people to create, but I'm also marshalling everybody, which is difficult for my creativity, as I'm like a referee. Everybody else is kicking a ball. It is very messy. From the mess, though, you refine what is there.

I try to push a single idea to its absolute limit. So for all of those ideas that existed in the story, you attempt to find a physical realisation in the space.

Haunted since the day its discovery was projected all over the world in 1994, I, like many others, have always wanted to see inside the Chauvet cave, site of the world's earliest known cave art. Quite rightly, we will never go. It is closed to the public.
