Power Up (shortened as PWR/UP) is the seventeenth studio album by Australian rock band AC/DC, released on 13 November 2020 through Columbia Records.

Power Up marks the return of vocalist Brian Johnson, drummer Phil Rudd and bassist Cliff Williams to AC/DC.

Malcolm received posthumous songwriting credits for all of the album's songs, as they were never-before released tracks written by him and his brother, Angus.

Prior to the tour, drummer Phil Rudd was charged with attempting to procure murder, threatening to kill, and possession of methamphetamine and cannabis.

[1] By 2016, lead singer Brian Johnson had started to suffer hearing loss, causing the final ten dates of the Rock or Bust tour to be rescheduled.

In 2018, rumours began circulating that AC/DC were working on their seventeenth studio album, with Johnson, Rudd, and Williams having returned to the group.

Johnson, Rudd, Angus Young and Stevie Young were photographed in August 2018 at Warehouse Studio, a recording studio in Vancouver, British Columbia, Canada owned by fellow musician Bryan Adams, suggesting the band were working where they had recorded their three previous albums.

[6][7][8] The rumours were later confirmed as the truth, with the album having been recorded there over a six-week period in August and September 2018 with producer Brendan O'Brien, who also oversaw 2008's Black Ice and 2014's Rock or Bust, with some tweaking having followed in Los Angeles in 2019.

[11] While promoting the album, Angus admitted that the songwriting process was difficult as he had to compile riffs that he had written with his brother Malcolm prior to his death in 2017.

[27] On 11 June 2021, the song "Through the Mists of Time" was released as a twelve-inch single, with "Witch's Spell" as the B-side as a part of Record Store Day.

"[37] Kitty Empire of The Guardian gave the album three stars out of five, stating, "If deja vu is a familiar sensation with AC/DC, few outfits have managed to eke so much variety out of so few constituent parts as these stalwarts of reductio ad absurdum.

observed, "AC/DC have made an album that, even for them, is a high-voltage celebration of life, the best of times, and the absolutely indomitable, boundless power of a couple of chords and a four-four beat.

In a time where getting together with your mates and partying and getting the beers in and shagging and living it up is all but illegal, as a reminder of just how powerful and timeless the very idea of these wonderful things are, AC/DC have never felt more necessary or vital.

[53] Additionally, the album's tracks accumulated a total 7.8 million on-demand streams in the week ending 28 November.
