It's a part of hip-hop, rave culture. But moving on from whistles, in the future we want to release Greco-Roman wine. Our friends are getting too old to go clubbing, but they will still have to buy our wine if we release it.

One of the big things right now is the DJ is a spectacle, isn't it? You have the enormous light show, smoke, explosions, and fire. There's a dude with a USB stick playing somewhere in there, but the spectacle is created out of lights and lasers and whatever. The original idea of DJing - being a shadowy figure in the corner while people were having a party - is not the one that makes money and is massively popular internationally.

I still love how Phil Spector turned teenage experiences into wonderful symphonies, but I find it a little more difficult to put myself in that place.

Right now, I don't particularly take different CDs or vinyl - I have my CD wallet that I take everywhere I go; there are different things in there that cater to different kinds of times - but if there's a special DJ thing coming up, I might go through my records and pick out this special selection. It's one the things that means you're improving as a DJ the more you do it, understanding what's going to go down well in a specific place.

The chemistry of making the songs is often about being inspired by each other and responding intuitively.

People try to be more edgy, or write about that first explosive meeting between two people in a club, but not so much the long-term issues; I don't know how to write a song about teenage heartbreak anymore.
