I still do mostly listen to CDs. I think that every format really is a different way of listening. If you take a different sort of psychological stance to it - like, I think the transition from vinyl to CD definitely marked a difference in the way people treated music. The vinyl commands a certain kind of reverence because it's a big object and quite fragile so you handle it rather carefully, and it's expensive so you pay attention to how it's looked after.

I'd love it if American kids were listening to Muslim music.

If you watch any good player, they're using different parts of their body and working with instruments that respond to those movements. They're moving in many dimensions at once.

Most big concerts sound disgusting and awful and insultingly bad. It's like going to the cinema and been shown a scratchy film which is upsidedown and the bulb had gone on the projector. The quality of large-scale live music is so shocking.

I think audiences are quite comfortable watching something coming into being.

It's not the destination that matters. It's the change of scene.

When you sing with a group of people, you learn how to subsume yourself into a group consciousness because a capella singing is all about the immersion of the self into the community. That's one of the great feelings - to stop being me for a little while and to become us. That way lies empathy, the great social virtue.
