Back in Black is the seventh studio album by Australian rock band AC/DC. It was released on 25 July 1980 by Albert Productions and Atlantic Records. It is the band's first album to feature lead singer Brian Johnson, following the death of previous lead singer Bon Scott.
 
After the commercial breakthrough of their 1979 album Highway to Hell, AC/DC was planning to record a follow-up, but in February 1980, Scott died from alcohol poisoning after a drinking binge. Instead of disbanding, they decided to continue on and recruited Johnson, who was previously vocalist for Geordie.
 
The album was composed by Johnson, Angus and Malcolm Young, and recorded over seven weeks in the Bahamas from April to May 1980 with producer Robert John "Mutt" Lange, who had worked on their previous album. Following its completion, the group mixed Back in Black at Electric Lady Studios in New York City. The album's all-black cover was designed as a "sign of mourning" for Scott.
As their sixth international studio release, Back in Black was an unprecedented success.
It has sold an estimated 50 million copies worldwide, and is the second best-selling album in music history.
The band supported the album with a yearlong world tour, cementing them among the most popular music acts of the early 1980s. The album also received positive critical reception during its initial release, and it has since been included on numerous lists of "greatest" albums.
Since its original release, the album has been reissued and remastered multiple times, most recently for digital distribution. On 9 December 2019, it was certified 25x Platinum by the Recording Industry Association of America (RIAA)
