Metallica's 1991 self-titled album is commonly nicknamed after which color?

Metallica’s 1991 self-titled album is commonly nicknamed The Black Album.

Officially titled Metallica, the record was the band’s fifth studio album and was released on August 12, 1991. Its nearly black cover features a dark Metallica logo and a coiled snake based on the Gadsden flag, making the nickname immediately memorable.

The album marked a shift from the rapid thrash-metal style of Metallica’s first four records toward slower, heavier and more polished songs. Producer Bob Rock helped shape the large, clear production, while tracks such as “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters” and “Sad but True” brought the band to a much wider audience.

The title can cause confusion because the album is officially just Metallica. “The Black Album” is an informal nickname, similar to how other self-titled records are identified by their cover color. It became one of the best-selling and most commercially influential metal albums ever released.
