AC/DC are an Australian rock band formed in 1973. They were founded by brothers Malcolm Young on rhythm guitar and Angus Young on lead guitar. Their music has been variously described as hard rock, blues rock and heavy metal, but the band calls it simply “rock and roll”. They are cited as a formative influence on the new wave of British heavy metal bands, such as Iron Maiden and Saxon. AC/DC were inducted into the Rock and Roll Hall of Fame in 2003.

AC/DC underwent several line-up changes before releasing their debut album, High Voltage (1975). Membership subsequently stabilised after the release of Let There Be Rock (1977), with the Young brothers, Rudd, Williams and Bon Scott on lead vocals. Seven months after the release of Highway to Hell (1979), Scott died of alcohol poisoning and the other members considered disbanding. However, at the request of Scott’s parents, they continued together and recruited English-born singer Brian Johnson as their new front man. Their first album with Johnson, Back in Black (1980), was dedicated to Scott’s memory. It became the second best-selling album of all time.
