AC/DC: Four decades of rock
AC/DC's co-founder Malcolm Young has died at the age of 64. A look back at the legendary band's career.
Made in Sydney
Born in Scotland, brothers Angus and Malcolm Young grew up in Sydney, Australia. Their band went through several line-up changes before releasing its first major studio album, "High Voltage," in 1976. Although the group was originally panned by Rolling Stone as a "gross-out" band, time has seen the LP attain classic status.
Old-time rock and roll
Some critics have said that AC/DC was the first major heavy metal band, and most would call the band hard rock - the Young brothers always insisted that their music was just good old rock and roll.
On the road
AC/DC embarked on their first major international tour alongside Black Sabbath in 1977, now with singer and lyricst Bon Scott (left), who would help the band skyrocket to worldwide acclaim. Scott died in 1980 at the age of 33.
Back in Black
After the success of 1979's "Highway to Hell," the following year AC/DC released the album that would define their career: Back in Black. With over 50 million copies sold worldwide, it is the second-bestselling album in history after Michael Jackson's "Thriller."
Rock is forever
AC/DC has gone through many ups and downs over the years, including losing drummer Phil Rudd after he was charged with trying to procure a murder. For the band's 2016 world tour, they announced that Guns N' Roses frontman Axl Rose would take over as lead singer.
Death of a legend
Malcolm Young has died at the age of 64. While the band has not announced a cause of death, Young retired from AC/DC in 2014 to receive treatment for dementia.
