In GLOBAL METAL, directors Scot McFadyen and Sam Dunn set out to discover how the West's most maligned musical genre - heavy metal - has impacted the world's cultures beyond Europe and North America. The film follows metal fan and anthropologist Sam Dunn on a whirlwind journey through Asia, South America and the Middle East as he explores the underbelly of the world's emerging extreme music scenes; from Indonesian death metal to Chinese black metal to Iranian thrash metal. GLOBAL METAL reveals a worldwide community of metalheads who aren't just absorbing metal from the West - they're transforming it - creating a new form of cultural expression in societies dominated by conflict, corruption and mass-consumerism.
