I wonder what sort of hot beats DJ Cobra Commander is spinning? These guys should know.

German DJ Nik Nowak created a special rig for his gigs. Fitting a sound system in the chassis, a control module in the "cockpit," and put the whole thing on tractor treads. If need be, he can even have the whole rig lift up and point the speakers towards the audience. The Autobots's Shockwave would be proud.
