"It was the perfect tragedy. Heavy metal albums found in their rooms, antisocial behaviour." How Lemmy, Corey Taylor, Henry Rollins and the metal community united to save three teenagers at the heart of a murder case that shocked America

The spirit of punk rock has always been at its best when fighting against oppression or supporting society's outcasts. Never has this been truer than in 2002, when a stellar cast of musicians from the world of punk, metal and rock joined forces to protest an appalling miscarriage of justice, using the songs of one of hardcore’s most legendary artists to raise funds to help put it right.

The project featured members of Slayer, Motörhead, Slipknot, Queens of the Stone Age, The Stooges, Public Enemy and many more, all singing the rebellious anthems of Black Flag to shine a light on the plight of three teenage metalheads, christened The West Memphis Three, who were facing life imprisonment and the death penalty between them after a miscarriage of justice that infuriated the rock community.
