To millions of fans AC/DC will always be the greatest hard rock band of them all. From their formation in Sydney, Australia in 1973 by brothers Angus and Malcolm Young, AC/DC have made the most visceral and single-minded rock, and inspired generations of rock icons from Def Leppard to Guns N' Roses and Metallica. The basic blueprint laid down in their early albums with Bon Scott – hard, no-nonsense, riff-driven rock'n'roll – has served them well with more than 200 million records sold, including the best-selling rock album of all time – Back in Black. Paul Elliott documents AC/DC's career from backstory to their latest album, 2014's Rock Or Bust, offering real insight into the band's enduring success and rise to rock royalty.
