The band made a surprise appearance at the Orion Festival
At the Orion Music Festival in Detroit on Saturday the 8th, Metallica surprised the audience by taking the stage for a surprise performance of their debut album, Kill 'Em All. The band was not on the festival's lineup that day, which was headlined by the Red Hot Chili Peppers.
In the schedule, the band Deehan was slated to play at that time, a possible pun on the name of the protagonist of the Metallica 3D movie
