David explains: "It's really simple. Me and my brother run the rock band Soulwax. He sings and I play guitars, then we DJ as 2 Many DJs playing mainly other people's music to make people dance."
David openly admits that the money from DJing is what lets them keep the band up. And that must have become a whole lot easier since the release of the 2 Many DJs album two-and-a-half years ago.
A mammoth piece of work, featuring 46 tracks and creating quite a sore head for the men charged with gaining clearance for them all, the album was a laid down version of the brothers' Hang The DJ show on the Belgian equivalent of Radio 1.
It was seized upon as one of the most cutting-edge works of that year and had the Daewales labelled as the next big thing.
"The mix album blew up, it made us into 'superstar DJs'," recalls David, tongue firmly in cheek.
"All of a sudden we were travelling the world, DJing everywhere. By doing that we could support the band."
2 Many DJs are still sitting at the top of the mash-up pile and in high demand but success does not seem to have altered the lads' laid-back attitude one bit.
"When it comes to DJing we really don't take things too seriously," says David. "When we started doing all this we did it as a sort of two fingers to dance culture - it's kind of funny now that we were rebelling against the whole mainstream music thing and now what we do has become the mainstream."
For all their joking that it pays the bills and that, "DJing is not rocket science," one thing that David and Stephen do genuinely have is a passion for music.
"If you want to be a DJ you should be really into the music that you play, then people will feel your enthusiasm. If you don't feel that people will see through it."
