Lamb of God, Anthrax, Deafheaven, and Power Trip are all out on the road together sonically destroying North America in a variety of ways. During the tour's stop at the Tabernacle in Atlanta, GA, on January 19, various members of each band got together and performed "United Forces" by the mighty Stormtroopers of Death!
What makes this extra cool is that Anthrax's guitarist Scott Ian and drummer Charlie Benante were both in Stormtroopers of Death, so this is probably the closest a lot of fans got to seeing the group live. Maybe if you go to another show from this tour, you'll see this cover (or more) again?
