Don't get me wrong. I hate short DJ sets. I prefer extended 2 hr+ sets but in a situation like this I can do some damage in 30 mins. Short sets in a situation like this makes the DJ give em what he/she has got and put it all on the line. We did a similar concept at an open turntable night back in the States called Trainwreck Tuesdays. Worked out well. We discovered a lot of new and talented individuals. As a result some of these "bedroom" DJs ended up getting regular bookings. Good stuff.
