Drummer Phil Rudd was unable to participate in the supporting tour after being sentenced to house arrest, being replaced by Chris Slade.

On 30 September 2020, after two years of rumours, AC/DC officially confirmed that Johnson, Rudd, and Williams had rejoined the band and that they have been working on a new studio album, Power Up, which was released on 13 November 2020, confirming that Rock or Bust would not be the final album to include Johnson, Rudd, and Williams.

While Malcolm has writing credits for every track on the album, all of his guitar parts were recorded by his nephew Stevie Young.

He brought about the idea that the album could be called Man Down, but believed the title might be too negative towards Malcolm's situation and overall health.

[9] The album was recorded at Warehouse Studio in Vancouver, Canada, with producer Brendan O'Brien and mixer Mike Fraser.

"[11] The songs were constructed largely by Angus Young from material accumulated by the brothers during the recording of previous albums.

[10] On some lead tracks, Angus Young used the Schaffer Replica, a device that emulates the Schaffer-Vega Diversity System.

[12] Josh Cheuse of the Arcade Creative Group handled the art direction, and decided to add more features to the physical edition, considering that "If you don’t make something special, there’s no point in even making any packaging at all.” Thus the cover is a lenticular, and the booklet has 24 pictures featuring the band.

[13] The agency Curb did a special video to promote the album in a Polish quarry, where a rock exploded to reveal a carved AC/DC logo.

Rudd was absent from both video shoots for the singles, and was replaced by Welshman Bob Richards, who had previously played with Man, Adrian Smith, Asia and Shogun.

[31] In particular, the magazine Trucking published a praising review by Andy Stewart in which he wrote, "Short, but definitely sweet, this long-awaited new album from Australia’s biggest band contains a raft of excellent riffs, signature screeching and rock ’n roll boogie-woogie rhythms that are all but impossible not to tap your feet along to.

"[32] As well, Charles Pitter of Popmatters commented that the album had "a keen focus on catchy choruses and riffs for those who are inclined to practice righteous, gnarly air guitar.

[34] As of January 2015, it has sold 500,000 copies in the US[35] leading to a Gold certification by the RIAA,[36] the band's 22nd album to reach such status.
