AC/DC is a hard rock band, formed in Sydney, Australia in 1973 by brothers Angus and Malcolm Young. The group is considered to be a pioneer of hard rock and heavy metal music along with Led Zeppelin, Deep Purple and Black Sabbath, but the members refer to their music as rock n roll. More than three decades into a career that shows no signs of slowing down or letting up, AC/DC, like electricity itself, provides the world with an essential source of power and energy. Since forming in 1973, AC/DC s high voltage rock n roll has flowed out into the world via consistently sold-out concert tours and global sales totaling more than 150 million albums and counting.
