Storming out of Australia's gritty pub scene in the mid ‘70s, AC/DC are the undisputed champions of high-decibel boogie minimalism. Their mechanised swing, first anchored by the Young brothers' razor-sharp riff dialogues, is so elemental that it essentially serves as the root DNA of the unholy trinity: heavy metal, hard rock and punk. Even when the quartet lost lewd and crude screamer Bon Scott in 1980, they didn't miss a beat. Bringing in the raspy-throated Brian Johnson, they unleashed Back in Black, a slab of brutal crunch and hip-shaking smut that turned them into permanent arena titans.
