Malcolm Young, rhythm guitarist and co-founder of the iconic rock band AC/DC, has died at the age of 64. Young had been suffering from dementia in recent years and left the group in 2014 due to his declining health.

A statement from the band reads, “Today it is with deep heartfelt sadness that AC/DC has to announce the passing of Malcolm Young. 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.”

Angus Young added, “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.”

The Young brothers co-founded AC/DC in 1973 and released their debut High Voltage two years later. The group saw multiple lineup changes over the years, most notably when singer Bon Scott died in 1980 shortly after the band broke through as superstars with Highway to Hell. His replacement, Brian Johnson, fronted the band as they continued to rise with albums such as Back in Black and For Those About to Rock We Salute You. AC/DC’s last album, 2014’s Rock or Bust, was their only without Malcolm Young, who co-wrote the songs on it, but his nephew Stevie Young played rhythm guitar.

Angus and Malcolm’s older brother George, who was a producer and musician in his own right, just passed away in October.
