A controversial guest appearance of Slipknot and Biohazard members during the set of Dj Rob Gee at the Dutch techno festival Sensation Black yesterday, has resulted in a stagefight. As Dutch newspaper 'De Telegraaf' reports, techno fans were already boo-ing the DJ away before his set had started. At around 02.00 a.m. Gee was about to start in his 90's Gabber hit 'XTC, You Got What I Need' and a visitor climbed the stage. Rob Gee felt threatened and went on a fist fight with the man. 

One day later Rob Gee reacted to the incident: "The guy came running at me and attacked me. I immediately had to think of my friend and former Pantera guitarist Dimebag Darrel. He got shot on stage."

Dutch website Geenstijl.nl came up with video footage of the incident, which can be viewed here and here.
