Pat Boone, a prominent American crooner, decides to cut a record of heavy metal classics. The idea sounds as strange as the record. This abstruse combination sets the parameters for Lohner's panoramic insight into an invincible genre personified by men in studded leather and cartridge belts. But the stereotype is subverted by a collage of intricate irony. Glimpses behind the scenes and into the private lives of famous long-haired family patriarchs open up some astonishing perspectives. Lohner assembles the cream of heavy metal: Ozzy Osbourne, Motörhead, Metallica, Venom, Sepultura and many more. They speak with great humour about their views on HM, showbiz, their roots and often surprisingly noble Ideals. But they are all stupefied to hear that THE Pat Boone choosed one of their songs to indulge his metal mood... A gem to end: Boone's big band playing "Smoke on the Water"
