Serj Tankian (System of a Down) and Mike Patton (Faith No More) have joined forces and contributed a song to the soundtrack for Body Of Lies.
 
Body of Lies is a new movie from long winded director Ridley Scott. The movie stars Russell Crowe and Leonardo DiCaprio. I have no idea what it is about, but you can listen to the collaboration at Serj's MySpace site:
