Metallica’s first album to top the charts, the Black Album, continues to be one of the most-sought-after for fans of the band’s style of metal. Shattering previous records for sales, the Black Album has sold an unprecedented amount of copies.

Since Nielsen SoundScan began to track album sales back in 1991, the Black Album has set the record for sales to date, at an incredible 16 million units. The news of the Black Album‘s continued success since its 1991 release comes at a nice time for the band. Metallica recently played the MusiCares Benefit show, which also featured Slash, Ozzy Osbourne, Dave Navarro, and Chad Smith. The band also has plans to join the Glastonbury Festival lineup as a headliner along with Arcade Fire, Dolly Parton, Jack White and others.

And this isn’t the only record the band has set, as they also lay claim to being the first group to tour all seven continents in a single year, a fun fact from you can find in this 2013 article on Metallica’s Freeze ‘Em All, a recording of a live performance in Antarctica.
