Powerage is the fifth studio album by Australian hard rock band AC/DC, released on 5 May 1978. It is also AC/DC's fourth international studio album. All songs were written by Angus Young, Malcolm Young and Bon Scott.
It was originally released on Atlantic Records, and reached No. 133 on Billboard's Pop Albums chart in the US, eventually going platinum. Powerage was re-released in 2003 as part of the AC/DC Remasters series.
Powerage is the first AC/DC album to be released nearly simultaneously in both Australian and international markets, and the first to use just one cover image for both. It was also the first to feature the same track listing on all versions, with the exception of the European vinyl edition (specifically, the first UK pressing of the LP). This version included "Cold Hearted Man", a song that was not previously released, and would not be released on any other AC/DC album until 2009's AC/DC Backtracks boxed set. The song became more widely available through the boxed set of Bon Scott-era vinyl LP albums in 1981. The song was packaged on a single-sided 12-inch single in the 1987 boxed set. The first UK pressing also includes different mixes than all later versions, most noticeably on "Down Payment Blues" (which excludes the bluesy coda heard on later pressings), "Kicked In The Teeth" (the opening chord was omitted on all other pressings but is present on the UK vinyl version) and "What's Next to the Moon," (which omits solos and backing vocals heard on later pressings.) In some territories, Powerage omitted "Rock 'n' Roll Damnation". This was due to a rushed job in getting the LP to pressing plants in time for the release date, hence "Rock 'n' Roll Damnation" (which was not yet completed) was omitted, "Cold Hearted Man" was added, and the rushed mixes are different from the 'finished' mixes that were thereafter used.
It was the band's last Bon Scott-era studio release to feature production work by Harry Vanda and George Young.
Powerage marked the studio debut of bassist Cliff Williams. Former bassist Mark Evans says that the album also has bass by him, as the Powerage songs started being done during the recording of his last album Let There Be Rock, and producer George Young, while Williams was having trouble on getting his work visa.
