Legendary Australian rock band AC/DC has teased a long-awaited comeback with a reunited line-up.

After several days of hints, the band’s official Twitter account posted a photo of the reformed band, which sees five experienced members together again for the first time since 2014.

Veterans of the band Angus and Stevie Young remain, while vocalist Brian Johnson, drummer Phil Rudd and bassist Cliff Williams each incrementally left the band following the release of Rock or Bust tour six years ago.

The promo shot carries the slogan PWR UP, which also featured in the teaser videos posted earlier in the week and on a poster spotted outside Angus Young’s old high school in Ashfield.

There were no hints of any impending tours or new music releases, but the tweet cryptically asked fans, “Are you ready?”.

AC/DC remains one of Australia’s greatest musical exports, with its unique hard rock style and aesthetic still immensely popular today, as are famous hits like Back in Black, Highway to Hell and It’s a Long Way to the Top.

Rock or Bust was AC/DC most recent studio album and was supported by a world tour throughout 2015 and 2016.

Rudd left the band in 2015 due to legal matters, while Johnson departed in 2016 after doctors order he stop touring immediately to save his hearing. Williams dropped out only months later, citing a change in dynamic as the make-up of the band shifted.

The band has been officially on hiatus since 2016, but rumblings have increased as to an imminent return to the stage, and Wednesday night’s announcement seems to have confirmed it.
