As American Authors were closing out their set at Vans Warped Tour on Saturday, GWAR decided to make a special-and bloody-appearance to help close out their set in typical GWAR fashion. American Authors later posted a video of the performance on their Facebook page along with, “It's all fun and games until GWAR murders your lead singer.”

This is not the first time GWAR have slayed a member of another band on stage. During Silverstein's set at the New Jersey Warped Tour stop, Beefcake the Mighty slayed the band's bassist before taking his place on stage. You can read the full story and watch the video here.
