Released on this day in 1980, Back in Black is the seventh studio album by AC/DC, and the group’s first with singer Brian Johnson.
To date, Back in Black has sold in excess of 40 million copies. It is the single biggest hard rock album ever released. It ranks #2 behind Michael Jackson's Thriller in worldwide sales.
For the opening of “Hells Bells” the band originally attempted to record the Denison Bell at England’s Carillon Tower and War Museum. Instead, producer Mutt Lange had a custom 2.000-pound brass bell created by a foundry that would remain perfectly in tune. Those flawless rings were eventually captured at Ronnie Lane’s Mobile Studio in England.
