AC/DC's classic 1980 album Back In Black has been certified 25 times platinum by the Recording Industry Association Of America (RIAA) for U.S. shipments of 25 million copies.

Back in Black first went platinum in October 1980 and had previously been certified 22 times platinum in December 2007. The RIAA lists the LP as the fourth biggest-selling album of all time.

The record was originally released on July 25th, 1980 and was the band's first without lead singer Bon Scott, who had died the previous February after drinking, passing out and choking on his own vomit. The band quickly decided to carry on and enlisted Brian Johnson as lead vocalist, a position he held until 2016.

Johnson told us a while back about his audition for the group: "I just went down and sang a couple of songs with the lads, but I remember I never thought I'd ever gonna get the job, you know, it was just a big thrill to go down. And I remember turning to the boys and saying, 'Hey, well, lads, I've got to get off' -- it was like 9:30 at night and I had to drive about 270 miles back home and start work the next morning, you know. So off I went, and Mal (Malcolm Young, guitarist) phoned us the next day and asked us if I fancied coming down and having another shot."

Back In Black made AC/DC into superstars in the U.S. and around the world, although it never got higher than Number Four on the album charts. The band's next album, 1981's For Those About To Rock...We Salute You, reached Number One.

Many of the songs from Back In Black became staples both on rock radio and in the band's set list, including "Hell's Bells," "You Shook Me All Night Long," "Shoot To Thrill" and the title track.
