By the mid-1980s, heavy metal had become a dominant force in American popular culture, prompting an intense moral backlash that framed the genre as dangerous and corrupting. This lecture examines how metal fans and musicians were cast as “folk devils” within the culture wars of the period, and how a cycle of horror films—including Trick or Treat and Black Roses—absorbed and refracted these anxieties. It argues that these films offered young audiences a space to critically engage with metal’s demonisation while exploiting its commercial and transgressive appeal.
