Australian rock band AC/DC formed in 1973, by brothers Malcolm Young (rhythm guitar) and Angus Young (lead guitar). Their current line-up comprises Angus, bassist Cliff Williams, drummer Phil Rudd, lead vocalist Brian Johnson and rhythm guitarist Stevie Young (nephew of Angus and Malcolm).
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 (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 Johnson as their new frontman. 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.
The band’s line-up remained the same for 20 years until 2014, when Malcolm retired due to early-onset dementia (from which he died three years later) and Rudd was involved in legal troubles. Malcolm was replaced by Stevie, who debuted on the album Rock or Bust (2014).
