Members of SLIPKNOT, MEGADETH, ANTHRAX, WHITESNAKE, POISON, RAGE AGAINST THE MACHINE, STRYPER, KORN, OVERKILL, KREATOR, SEPULTURA and VOLBEAT are among the rock musicians and scores of other artists who reacted on social media to the passing of Malcolm Young.

The 64-year-old guitarist and co-founder of the legendary Australian hard rock band AC/DC had been suffering from dementia for at least the past three years.

Malcolm died peacefully on Saturday with his family by his bedside, a statement said.

Malcolm Young struggled with the onset of dementia for a period of time prior to being admitted to full-time nursing care in Sydney, Australia beginning in 2014.

Malcolm was replaced in AC/DC by Stevie Young, nephew of Malcolm and AC/DC guitarist Angus Young.

Malcolm did not participate in the recording sessions for AC/DC‘s latest studio album, “Rock Or Bust”, which arrived in December 2014.

Malcolm Young was faced with two other massive health scares after the conclusion of the group’s marathon 20-month tour in support of 2008’s “Black Ice” album. First, he was diagnosed with lung cancer, which was detected early, enabling surgeons to operate on the guitarist successfully. Then he discovered he had a heart condition.

Malcolm‘s death came just weeks after his brother George Young, guitarist for THE EASYBEATS and AC/DC producer, died at age 70.

Malcolm is survived by his wife, two children and three grandchildren.

It is a sad day in rock and roll. Malcolm Young was my friend and the heart and soul of AC/DC. I had some of the best times of my life with him on our 1984 European tour. He will be missed and my deepest condolences to his family, bandmates and friends.

I was dreaming of Malcom Young when I was woken by a text message of his death. Malcom was the diesel that powered the locomotive that had such impact on me. I was lucky to have met him on a few occasions. He was always very nice. I’m happy he is at peace.
