Malcolm Young

Malcolm Mitchell Young (6 January 1953 - 18 November 2017) was an 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[by whom?] 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.
