Metallica first reached number one on the US Billboard 200 with its 1991 self-titled album.
The record debuted at number one and stayed there for four consecutive weeks. It was the band's first album to top that chart, following the number-six peak of ...And Justice for All in 1988.
Its chart performance reflected more than the strength of one single. The album built momentum through several successful songs, extensive touring, and a cleaner, more accessible production style that brought Metallica to a much larger audience.
The title can cause confusion because fans usually call the album The Black Album. “Metallica” is the official title, and it is the title used in chart records and discographies.
