Packed with all-star interviews, rare photos, the film tells the story of the groundbreaking 1982 Metal Massacre vinyl compilation-a sonic celebration of the burgeoning Los Angeles Metal scene, which helped launch the careers of iconic acts Metallica and Ratt, and ultimately led to the birth of the legendary independent record label Metal Blade Records. The film boasts priceless commentary and anecdotes from Metal Blade founder Brian Slagel and his friend and collaborator John Kornarens, two metalheads with a dream who made Metal Massacre a reality; as well as Metallica members Lars Ulrich and James Hetfield; Ratt frontman Stephen Pearcy; and Black N’ Blue singer Jamie St. James, among many others.
