Maybe that's where the new art comes in - to somehow have your eye on the marketplace and harness your art to come up with something you can be proud of creatively.

I felt from time to time that shooting live music is the most purely cinematic thing you can do. Ideally, the cinema is becoming one with the music. There is little artifice involved. There's no acting. I love it.

Music films are great, but they can never compete with a live performance. Live music is what it is. It's the whole point. You experience it in the moment.

I also feel that the only thing more gratifying than working with someone who you've worked well with is working with someone new and coming up with something great.

Everything I've made - it doesn't mean they've all been good - but everything I've made so far, big or little, fiction or documentary, has been something that I've been really enthusiastic about.

I love doing fiction. I love doing performance films and I love doing documentaries that don't have music. I love to shoot and I love to shoot things I'm enthusiastic about.

I had very strong feelings, so the chance to make a film that deals in an imaginative way with stuff you care tremendously about is a real high. It's a really amazing thing to be able to do.
