History of Hard Rock/Heavy Metal: AC/DC

AC/DC's mammoth power-chord roar became one of the most influential hard rock sounds of the '70s. In its own way, it was a reaction against the pompous art rock and lumbering arena rock of the early '70s. AC/DC's rock was minimalist — no matter how huge and bludgeoning the guitar chords were, there was a clear sense of space and restraint. Combined with Bon Scott's larynx-shredding vocals, the band spawned countless imitators over the next two decades.

AC/DC was formed in 1973 in Australia by guitarist Malcolm Young after his band, the Velvet Underground, collapsed (Young's band has no relation to the seminal American group). With his younger brother Angus as lead guitarist, the band played some gigs around Sydney. Angus was only 15-years-old at the time and his sister suggested that he should 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 band. The band's chauffeur, Bon Scott, became their lead vocalist when their singer, Dave Evans, refused to go on-stage.

The group released two albums — High Voltage and TNT — 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. Evans left the band at the beginning of 1977, with Cliff Williams taking his place. In the fall of 1977, AC/DC released Let There Be Rock, which became their first album to chart in the U.S.

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 20, 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, the band 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, the band was 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 1982, Rudd left the band; he was replaced by Simon Wright.

While not the commercial powerhouse they were during the late '70s and early '80s, the '90s saw them maintain their status as a top international concert draw.
