On 3 April 1977, AC/DC filmed a live performance of "Dog Eat Dog" for Australia's Countdown. In July 1977, the band further promoted Let There Be Rock by filming a music video for the album's title track. Recorded in a church in Sydney's Surrey Hills known as the Kirk Gallery, it featured Scott as a priest and the rest of the band as altar boys.
The album cover features an image of Buffalo's Chris Turner's fingers on a guitar neck. This edition was eventually repackaged with the international version's cover (see image), marking the first time an Australian AC/DC album cover was matched to its corresponding international edition.
As with AC/DC's previous albums, there are differences between Let There Be Rock's Australian and ultimate international editions. The original vinyl version of the album made available for international release contained the same tracks as the Australian release. However, Atlantic Records removed the racy "Crabsody In Blue" (about the problems of crabs) from the later international version. It was replaced with a shortened version of "Problem Child" from the Australian version of the album Dirty Deeds Done Dirt Cheap, released in September 1976. "Crabsody In Blue" was later released on the box set Backtracks, which was released in 2009. All international CD releases contain the modified track listing.
The international version's cover also marked the debut of the band's logo, designed by Gerard Huerta. The photograph used for the cover was taken on 19 March 1977 at the Kursaal Ballroom, Southend, Essex, UK.
Reception to Let There Be Rock was generally positive; according to Allmusic, which gave the album a rating of four and a half out of five stars, AC/DC played "sweaty, dirty, nasty rock" and the band had "rarely done that kind of rock better than they did" on Let There Be Rock. In 2001, Q magazine named Let There Be Rock as one of the 50 Heaviest Albums Of All Time.
