Metallica became the band’s first number-one album on the Billboard 200.
Released on August 12, 1991, the self-titled record reached the top of the US album chart for the first time in Metallica’s career. It debuted with approximately 598,000 copies sold in its first week and was certified platinum within two weeks. The album’s commercial impact helped establish the band as a global mainstream act.
The record’s success was especially notable because it followed four albums associated with a more aggressive thrash-metal style. Producer Bob Rock helped the band create a slower, heavier, and more polished sound, while singles such as “Enter Sandman” expanded its audience.
The album is commonly called The Black Album because of its minimalist black cover, but “Metallica” is its official title. That distinction matters when comparing the band’s discography: Master of Puppets, Ride the Lightning, and ...And Justice for All all preceded it, but none had reached number one on the Billboard 200. The record later became one of the best-selling albums of the SoundScan era.
