Malcolm Young, the greatest hard rock rhythm guitarist is too ill to play. Now, the greatest hard rock frontman, Brian Johnson is no longer able to tour because he will lose his hearing if he continues the 2016 World Tour. They say Axl Rose could replace Brian but he can’t be replaced. My gut was right when I decided against getting tickets to see ACDC play at MSG this April. ACDC is done but they will live on as all great bands do.
