Metallica recently played a very special show in a dome on Antarctica. Only about 120 people got to see in. And In order to meet international Antarctic protocol to preserve the fragile local environment, Metallica played the whole show with no amplification. The sound was transmitted to the audience through headphones.
The series is being produced by Avenged Sevenfold themselves, in conjunction with Machinima and Metalocalypse director Jon Schnepp. The series is set for 6 episodes.
