Heavy metal musicians aren’t just harbingers of doom. They are also voices of social consciousness. In this talk, I provide over 40 years of songs on the threats of nuclear war, globalization, the invasion of Iraq, demagogue politicians, and human-caused climate change. From Black Sabbath to Lamb of God, from Metallica to Forbidden and Xentrix, from Kreator to Revocation, bands have raised our consciousness and spoken to our conscience. How? By addressing power with powerful music.
Watch.
