Mayhem is pretty fucking metal, but we're not talking about its pioneering of black metal in Norway. There's the bootleg live-album cover art featuring the body of the vocalist aptly named "Dead" after killing himself. Then there was the murder of guitarist "Euronymous" by former member Varg Vikernes. And then there's all those churches they allegedly burned, and all those severed pigs' heads they throw around onstage. We could go on.
