Whats the coolest thing DJ did during a concert?

The coolest things are the Dj battle offs between Diplo and anybody else like Dj Diablo etc. Type in Diplo on you tube and check it out. Check out "Make you Pop" and also Diplo vs. Tiesto on "Come on". They are in a cl of thier own. I especially like the laser shows Diplo does like at Spookfest live 2009.
