AC/DC are an Australian rock band formed in 1973. They were founded by brothers Malcolm Young on rhythm guitar and Angus Young on lead guitar. Their current line-up comprises Angus, bass guitarist Cliff Williams, drummer Phil Rudd, lead vocalist Brian Johnson and rhythm guitarist Stevie Young, nephew of Angus and Malcolm. Their music has been variously described as hard rock, blues rock and heavy metal, but the band calls it simply "rock and roll". They are cited as a formative influence on the new wave of British heavy metal bands, such as Def Leppard and Saxon. AC/DC were inducted into the Rock and Roll Hall of Fame in 2003.
