If you’re a dubstep DJ, then you’re obviously looking for the kinds of gigs where you can come in and play a set of what you’re into…rather than taking requests and playing pop all night.
If I’m wrong, I apologize.
However, if I’m right, then those gigs go to the guys who can bring out people to a club…or at least be able to play a solid opening set for a bigger name.
I’d tell you to hang around the UK message boards, Facebook pages, groups, etc…dedicated to Dubstep. Post mixes, get into production and post tracks. Make a press kit and send demos to promoters. You just have to do the leg work. Maybe do freebies for rave promoters who need DJs, but are low on funds.
