Nov. 18 (UPI) -- AC/DC co-founder Malcolm Young has died after a long battle with dementia. He was 64.
"Today it is with deep heartfelt sadness that AC/DC has to announce the passing of Malcolm Young," the band's official Facebook page said Saturday.
"Malcolm, along with Angus, was the founder and creator of AC/DC. With enormous dedication and commitment he was the driving force behind the band. As a guitarist, songwriter and visionary he was a perfectionist and a unique man. He always stuck to his guns and did and said exactly what he wanted. He took great pride in all that he endeavored. His loyalty to the fans was unsurpassed."
"As his brother it is hard to express in words what he has meant to me during my life, the bond we had was unique and very special. He leaves behind an enormous legacy that will live on forever. Malcolm, job well done," Angus Young added.
The BBC said Malcolm Young is credited with writing some of the Australian heavy metal group's most famous songs such as "Back in Black," "Highway to Hell" and "You Shook Me All Night Long."
Malcolm Young retired in 2014 after his dementia diagnosis.
