As you may know, AC/DC's frontman Brian Johnson had to cancel touring plans due to the threat of permanent hearing damage. Following that, there was speculation that AC/DC was going to continue to tour without Johnson who has fronted the band since 1980, following the death of second lead singer, Bon Scott. Well, the remaining members of AC/DC have announced that for their upcoming summer tour, Axl Rose of Guns N Roses will serve as their vocalist. In fact, AC/DC's guitarist Angus Young recently appeared at GNR's Coachella performance. See that below.
