Malcolm Young, R.I.P.

Malcolm Young, the rhythm guitarist and principle co-writer for AC/DC, has died following a long battle with dementia. He was 64.

While he didn't have the same public profile as his younger brother Angus or lead singers Bon Scott and Brian Johnson, Young put the AC into the DC.

Young's illness began in 2010 and forced him out of the band altogether by 2014.

His death comes less than a month after that of his older brother George Young who was the group's original producer and previously a member of the 1960's pop group The Easybeats.
