Mastodon's Brent Hinds will appear on the upcoming season of Game Of Thrones.

"I just came back from my second cameo Game of Thrones. This time, I had my broken leg and they were like 'you're doing the best zombie walk, we want you to come right towards the camera. I want you to drag this axe behind you.' I'm like a reborn, come to life wildling turning into a White Walker."
Season 7 of Game of Thrones will premiere on July 16.
