Focusing on how the artform incorporates Viking melodies, lyrics inspired by mythology and socially unacceptable (and often violent) behavior, the film reveals the truth about a mysterious subculture. With insights from black metal groups Mayhem, Bathory, and Immortal. 80 min. Standard; Soundtrack: English Dolby Digital stereo.
