With a limitless supply of dirty riffs, snarling vocals, and timelessly catchy, anthemic choruses, AC/DC is one of the most important and most lasting forces in hard rock. Founded in the early '70s by Scottish-born brothers Malcolm and Angus Young, the Aussie band exploded onto the international stage in 1979 with the release of their multi-platinum-selling sixth album, Highway to Hell. The death of charismatic frontman Bon Scott in 1980 threatened to derail the group, but AC/DC powered through. They recruited Geordie vocalist Brian Johnson and unleashed their most successful effort to date, Back in Black, which has become the second best-selling album in history. The band continued to help define the sound of hard rock and metal throughout the '80s, '90s, and beyond, spawning countless imitators and enjoying steady, consistent commercial success. They also became one of the best examples of arena rock, playing to enormous crowds as the years went on, and rocking as hard as ever on studio albums like 1990's pop-glinted The Razor's Edge and 2020's Power Up, both of which reached the upper tiers of multiple charts. AC/DC were formed in 1973 in Australia by guitarist Malcolm Young after his previous band, the Velvet Underground, collapsed (no relation to the seminal American group). With his younger brother Angus serving as lead guitarist, the band played some gigs around Sydney. Angus was only 18 at the time, and his sister suggested that he wear his school uniform on-stage; the look became the band's visual trademark. While still in Sydney, the original lineup featuring singer Dave Evans cut a single called "Can I Sit Next to You," with ex-Easybeats Harry Vanda and George Young (Malcolm and Angus' older brother) producing. The band moved to Melbourne the following year, where drummer Phil Rudd (formerly of the Coloured Balls) and bassist Mark Evans joined the lineup. The band's chauffeur, Bon Scott, became the lead vocalist when singer Dave Evans refused to go on-stage. Previously, Scott had been vocalist for the Australian prog rock bands Fraternity and the Valentines. More importantly, he helped cement the group's image as brutes -- he had several convictions for minor criminal offenses and was rejected by the Australian Army for being "socially maladjusted." AC/DC were socially maladjusted. Throughout their career they favored crude double entendres and violent imagery, all spiked with a mischievous sense of fun. The group released two albums -- High Voltage and T.N.T. -- in Australia in 1974 and 1975. Material from the two records comprised the 1976 release High Voltage in the U.S. and U.K.; the group also toured both countries. Dirty Deeds Done Dirt Cheap followed at the end of the year. In the fall of 1977, AC/DC released Let There Be Rock, which became their first album to chart in the U.S. Mark Evans left the band soon after, with Cliff Williams taking his place. Powerage, released in spring of 1978, expanded their audience even further, thanks in no small part to their dynamic live shows (which were captured on 1978's live If You Want Blood You've Got It). What really broke the doors down for the band was the following year's Highway to Hell, which hit number 17 in the U.S. and number eight in the U.K., becoming the group's first million-seller. AC/DC's train was derailed when Bon Scott died on February 19, 1980. The official coroner's report stated he had "drunk himself to death." In March, the band replaced Scott with Brian Johnson. The following month, they recorded Back in Black, which would prove to be their biggest album, selling over ten million copies in the U.S. alone. For the next few years, they were one of the largest rock bands in the world, with For Those About to Rock We Salute You topping the charts in the U.S. In 1983, Rudd left after the recording of Flick of the Switch; he was replaced by Simon Wright. With Flick of the Switch, AC/DC's commercial standing began to slip, and they weren't able to reverse their slide until 1990's The Razor's Edge, which spawned the hit "Thunderstruck." While not the commercial powerhouse they were during the late '70s and early '80s, the '90s saw AC/DC maintain their status as a top international concert draw. In the fall of 1995, their 16th album, Ballbreaker, was released. Produced by Rick Rubin, the album received some of the most positive reviews of AC/DC's career; it also entered the American charts at number four and sold over a million copies in its first six months of release. Stiff Upper Lip followed in early 2000 with similar results. AC/DC signed a multi-album deal with Sony in 2001 that resulted in a slew of reissues and DVDs, and they returned to the studio in 2008 for Black Ice, an all-new collection of songs that topped charts in numerous countries (including Australia, the U.S., and the U.K.) and was followed by the group's first world tour since 2001. Two years later, the band's music was featured heavily in the action movie Iron Man 2, and a compilation was released in conjunction with the film under the title Iron Man 2. As AC/DC began work on a new album with producer Brendan O'Brien in 2014, they announced that Malcolm Young was suffering from dementia and had left the band; his nephew Stevie Young took his place at recording sessions and the accompanying 40th anniversary tour, and subsequently joined the group full-time. Just prior to the December release of Rock or Bust, drummer Phil Rudd was arrested under charges of attempting to procure a murder, threatening to kill, and possession of cannabis and methamphetamine. Although the arranged murder charges were dropped, the others remained and the drummer's future with the band was uncertain. Nevertheless, AC/DC marched forward with the release of Rock or Bust and plans for a tour in 2015. In 2017, Malcolm Young died in November at the age of 64. Following a two-year hiatus, the band reunited with producer Brendan O'Brien for their 17th studio album, Power Up, which became their third consecutive number one album in Australia and their third chart-topper in the U.S. ~ Stephen Thomas Erlewine, Rovi
