Founding member of AC/DC Malcolm Young has died, according to the band's official Facebook page. Malcolm, with his brother Angus, founded AC/DC in 1973. He left the band in 2014 as a result of dementia.
Although Angus Young is seen as the face of the band, Malcolm was always considered the driving force behind AC/DC. He wrote or co-wrote many of the band's best guitar riffs.
Malcolm appeared on every AC/DC album except 2014's Black Ice.
He was 64 years old and is survived by a wife and two children.
