Megadeth played a very rare acoustic set for WRIF radio in Auburn Hills, Michigan last week, which was also broadcast live on the web. Here's the full performance, which includes "Public Enemy No. 1," "Angry Again," "A Tout le Monde" (featuring Cristina Scabbia of Lacuna Coil), "Symphony of Destruction" and "Use the Man." Enjoy!
