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. Sony BMG Music Entertainment's #1 best-selling catalog act worldwide, AC/DC has sold nearly 70 million albums in the U.S. alone, making AC/DC one of the five top-selling bands in American music history.
