Malcolm Mitchell Young (born 6 January 1953 in Glasgow, Scotland) is a retired Australian musician and songwriter of Scottish origin, best known as a co-founder, rhythm guitarist, backing vocalist and songwriter for the Australian hard rock band AC/DC. Except for a brief absence in 1988, he was with the band from its November 1973 beginning until retiring permanently in 2014, due to health reasons. Young and the other members of AC/DC were inducted into the Rock and Roll Hall of Fame in 2003. Though his younger brother Angus is the more visible of the brothers, Malcolm has been described as the businessman behind AC/DC. As the rhythm guitarist, he was responsible for the broad sweep of the band’s sound, developing many of their guitar riffs and co-writing the band’s material with Angus. He is married to Linda Young and has two children, Cara and Ross. Young took a leave of absence from AC/DC in April 2014, to receive treatment for dementia. In September 2014, the band’s management announced that he would be retiring permanently.
