Input: Malcolm Young   whose crunching guitar provided the rhythmic backbone of AC/DC for more than 40 years  died on Saturday at the age of 64.
 Young  who co-founded the Australian hard rock band with his younger brother Angus in 1973   stuck with the band â and  by most accounts  served as its leader â until  he  retired in 2014.  His  retirement was prompted by the onset of dementia.
 The band  confirmed  Young 's passing in a statement posted to  its  Facebook page. The post also includes a second  more personal statement from Angus himself.

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. â Eddie Van Halen (@eddievanhalen) November 18  2017
