The Army of the Dead just got more hardcore.
Brann Dailor, Bill Kelliher and Brent Hinds of the heavy metal band Mastodon appeared on Game of Thrones Sunday night as Wildlings.
Their scruffy appearance clearly made them shoo-ins for rough battle scenes.
As is tradition in Westeros, their time as free folk did not last very long as they died only to rise again as wights; the dread White Walkers from beyond the Wall.
Of course, the band seemed perfectly happy to be among Jon Snow and the rest of the cast and crew, who filmed their scene in Northern Ireland.
Mastodon recorded an original song, “White Walker,” as part of the Catch the Throne Vol. 2 mixtape for the television series.
