Book excerpt: Myth pervades heavy metal. With visual elements drawn from medieval and horror cinema, the genre's themes of chaos, dissidence and alienation transmit an image of Promethean rebellion against the conventional. In dialogue with the modern world, heavy metal draws imaginatively on myth and folklore to construct an aesthetic and worldview embraced by a vast global audience. The author explores the music of Black Sabbath, Iron Maiden, Judas Priest, Metallica and many others from a mythological and literary perspective.
