Brian Johnson of AC/DC

In March 2016, the world was shocked when Brian Johnson announced – mid-tour – that he could no longer continue performing with rock legends AC/DC. On advice from his doctors, Johnson was forced to bow out owing to issues with his hearing and further exposure to loud volumes would’ve resulted in eventual total hearing loss. AC/DC went on to recruit Guns N’ Roses’ Axl Rose to complete the rest of the tour.

However, Johnson doesn’t seem like he wants to retire without a fight. Just months after the announcement, he revealed that he’d been working with an in-ear technology company to come up with a fix and that things looked very promising. This year, Johnson returned to live performances, singing with Robert Plant and Paul Rodgers at a Bad Company concert this May.

Last night, at their headlining set at the Reading Festival in the UK, British progressive rockers Muse invited Johnson onstage for a cover of AC/DC’s classic ‘Back In Black’, with Johnson bringing his signature gravel-voiced energy to the raucous performance. Posting about the performance, Muse said, “Such an honor to have the legendary Brian Johnson join us onstage at Reading Festival last night. Thanks so much Brian!”

What does this mean for Johnson and AC/DC? There’s no news on that yet, but stay tuned.
