Former Ozzy Osbourne guitarist Gus G. called Young "co-founder Of the greatest Rock n Roll band ever".
Dream Theater's Mike Portnoy wrote, "Wow.just got off stage here in Brisbane, Australia (of all places) to the shocking news of Malcolm Young's passing". "Malcolm, along with Angus, was the founder and creator of AC/DC".
Malcolm and Angus' older brother George, who paved the way for his siblings with legendary 1960s group The Easybeats before finding further success as a songwriter and producer with ex-bandmate Harry Vanda, died last month aged 70.
"The bond we had was unique and very special", Angus explained.
"He was older than me - I always looked up to him", Angus Young said of his brother in an interview past year with Rolling Stone Magazine, saying he was "always one to battle through".
The band concludes the message with a simple tribute to Malcolm stating that the guitarist "leaves behind an enormous legacy that will live on forever". Young had been battling dementia for three years and was replaced by his nephew, Stevie Young, in the 2015 AC/DC world tour.
"Malcolm had been suffering from Dementia for several years and passed away peacefully with his family by his bedside". "Malcolm, job well done", he said, according to Rolling Stone. The albums were produced by brother George and his songwriting partner Harry Vanda, who brought out the pop sensibilities in the band's crushing template.
In 2013, the Rock & Roll Hall of Fame inducted AC/DC.
Some of the band's most popular songs include "Back in Black", "Thunderstruck", "Hells Bells", "You Shook me all Night Long" and "For Those About to Rock".
He is survived by his wife O'Linda and two children.
