Brian Johnson

AC/DC singer joins Dave Grohl's band for Global Citizen's 'Vax Live: The Concert to Reunite the World.'

"I've gone from choirboy to rock 'n' roll singer," he says. "And now I've gone and written a bloody book about it."

It goes back to before he joined AC/DC.

Singer recalls “apprehension” as he attempted rehearsal with cutting-edge hearing technology.

Singer says “Through the Mists of Time” is the ‘Power Up’ track where Malcolm Young’s presence is most evident.

For those about to rock.

Fire!

'It was crippling. There's nothing worse than standing there and not being sure,' said Johnson of his hearing loss.

Singer celebrates band’s “electricity" in making of new LP.

An experimental procedure aided the singer's comeback.

Three members who left the band at various points during the 'Rock or Bust' tour have returned.

Power up!
