In “GLOBAL METAL,” filmmakers Scot McFadyen and Sam Dunn embark on a quest to uncover the influence of heavy metal, a frequently criticized Western music genre, on cultures outside of Europe and North America. The documentary tracks metal enthusiast and anthropologist Sam Dunn as he embarks on an exhilarating expedition across Asia, South America, and the Middle East. During his travels, he delves into the underground extreme music scenes, encountering everything from Indonesian death metal to Chinese black metal and Iranian thrash metal. “GLOBAL METAL” uncovers a global network of metal enthusiasts who are not merely adopting Western metal but are reshaping it, forging a novel form of cultural expression in societies often marked by conflict, corruption, and rampant consumerism.
