List of awards and nominations received by AC/DC: AC/DC are a hard rock band formed in Sydney, Australia in 1973 by brothers Angus and Malcolm Young.  Although the band are considered pioneers of heavy metal, its members have always classified their music as "rock 'n' roll".  AC/DC underwent several line-up changes before releasing their first album, "High Voltage", in 1975.  Membership remained stable until bassist Cliff Williams replaced Mark Evans in 1977.  In 1979, the band recorded their highly successful album "Highway to Hell".  Lead singer and co-songwriter Bon Scott died on 19 February 1980, after a night of heavy alcohol consumption.  The group briefly considered disbanding, but soon ex-Geordie singer Brian Johnson was selected as Scott's replacement.  Later that year, the band released their best-selling album, "Back in Black".  The band's next album, "For Those About to Rock We Salute You", was also highly successful and was their first album to reach number one in the United States.  AC/DC declined in popularity soon after the departure of drummer Phil Rudd in 1983.  Poor record sales continued until the release of "The Razors Edge" in 1990.  Phil Rudd returned in 1994 and contributed to the band's 1995 album "Ballbreaker". " Stiff Upper Lip" was released in 2000 and was well received by critics.
