Fly on the Wall is the tenth studio album by Australian hard rock band AC/DC, released on 1 July 1985 by Albert Productions, and Atlantic Records.

In October 1984, Atlantic Records released to the United States the EP '74 Jailbreak, a collection of studio tracks previously unreleased outside Australia, taken mainly from the band's 1975 Australian debut High Voltage.

[8] The singles "Shake Your Foundations" and "Sink the Pink" are seen as standouts;[3][9][10] both were later included on the band's soundtrack album Who Made Who for Stephen King's film Maximum Overdrive.

"[12] According to Steve Huey of AllMusic, "Fly on the Wall continues AC/DC's descent into cookie-cutter mediocrity, with the leering humor of past glories seeming forced and uninspired, and the music remaining somewhat underdeveloped and directionless.

Martin Popoff observed how Fly on the Wall "tries desperately to recapture wasted youth, yet the material for the most part is cookie-cutter AC/DC" and remarked Brian Johnson's awkward vocals "mixed quite far back, possibly because he's sounding raspier and more incoherent than ever".

Classic Rock explains that Malcolm and Angus Young "made AC/DC sound like a tribute act on a bad night, and as writers all they could muster was one half-decent song, Shake Your Foundations.

As Murray Engelheart observes in his book AC/DC: Maximum Rock & Roll, "It was just what the band's detractors had been waiting for and the media, especially in America, immediately seized on the case.

The lyrics of 'Night Prowler' were carefully analysed and some newspapers attempted to link Ramirez's Satanism with AC/DC's name, somehow arriving at the conclusion that AC/DC actually stood for Anti-Christ, Devil's Child."
