james,
Sander and Bill Patrick did back to back for about 4 hours. Absolutely wicked. Bill is a DJ to watch, amazing bass-heavy tech-house, spotless mixing. The vibe was spot on -- like the best house party you'll ever have. In between dancing for 6 hours straight (no enhancements, mind you) got a chance to to talk to both DJs. Left the party grinning ear to ear.
