Metallica won the Grammy for its self-titled album in 1992.
The album won the Grammy Award for Best Metal Performance at the 34th Annual Grammy Awards. The victory recognized Metallica's 1991 self-titled release, which is widely known as The Black Album.
The award arrived during the album's rapid rise to international prominence. Metallica had previously been nominated for a Grammy for ...And Justice for All, and the band had won for “One” in 1990 and “Stone Cold Crazy” in 1991.
This award is sometimes confused with later Grammy wins for individual songs. The 1992 honor went to the album itself in the Best Metal Performance category, while “Enter Sandman” was separately nominated for Best Rock Song and won an MTV Video Music Award for its video.
