Malcom Young, the guitaritst and co-founder of Australian rock band AC/DC passed away on Saturday [November 18] at the age of 64.

It was Malcolm and his brother Angus who would come together in 1973 to form one of Rock's most influential groups, known for great energy and legendary guitar riffs, that came courtesy of Young himself, bringing notoriety and finding great success in tracks such as "Highway To Hell," "Back In Black," and "Thunderstruck."

"Malcolm had been suffering from Dementia for several years and passed away peacefully with his family by his bedside," reads a statement on the band's official website.

It was about three years ago that the band announced Young's departure to receive treatment for dementia. He would soon retire permanently.

"Renowned for his musical prowess Malcolm was a songwriter, guitarist, performer, producer and visionary who inspired many," the statement continues. "From the outset, he knew what he wanted to achieve and, along with his younger brother, took to the world stage giving their all at every show. Nothing less would do for their fans."

"For those wishing to send messages to the family please visit the Sydney Morning Herald Malcolm Young Memorial website which will be available next week. The family have asked instead of flowers to send donations to The Salvation Army."
