When bands are on stage and they ask the crowd, "Are you having a good time?" what they're really saying is, "I just want a bit of reassurance - is everything all right?"

I think being a DJ is that thing of learning what makes a crowd move. As a DJ, you're constantly learning. It's like chess or something. After a couple of years, you think you're good, then you see a real DJ that's been doing it for 20 years and they just blow you away. I think that's one of the things I like about DJing: you can get better and better and better.

When I first started doing stuff outside of Hot Chip, I got the impression that Joe Goddard was a bit concerned. But I said, "I really want to record these songs quickly and not turn them into dance music." And he was fairly supportive - maybe not wholly supportive. But then you learn that no one's about to quit the band, so it seems good and healthy.

A lot of people in the crowd want to be told what to do; if you just put your hands up, they do it.

I really enjoy playing for hours and hours. DJ sets where you turn up over an hour and you're on a festival stage, people basically expect much more pounding than I ever would play. I just feel like a fish out of water when I do those. They want something really kind of aggressive; that's not really the kind of music that I'm into.

I find it really disappointing and cheap when someone's copied the whole drum sound from a record.

There's another thing that you don't want to take for granted, and that's the reality of there being an audience there each night. It's pretty amazing that that can happen around the world.
