Rumors about musician Mike Patton's involvement in the highly anticipated summer sequel Transformers: Revenge of the Fallen were confirmed today by a "close" friend of the singer (who may or may not live in Philadelphia). More of a cameo than a leading robot, Patton will lend his unique vocal talents to Mixmaster, one of the seven Decepticons that form to create Devastator. He is a concrete mixing truck that serves as the left leg of this gigantically awesome robot.

While Patton's participation in the film was 100% confirmed, the "source" didn't seem quite so positive about the actual robot he would be playing, at times calling him a dump truck (which is actually Long Haul). Either way, he will voice one of the seven vehicles that form Devastator. Patton is said to have landed the gig after producers heard his voice work on the video game The Darkness. This is a big year for the prolific singer, as his score for Crank: High Voltage will be released this coming Tuesday. And he is currently in the midst of embarking on a European reunion tour with his former band Faith No More.
