Which record label released Metallica's The Black Album in the United States?

Elektra Records released Metallica's The Black Album in the United States.

The 1991 album appeared through Elektra, the label associated with Metallica during the band's breakthrough into global mainstream success. International editions were also connected with regional partners and distributors, including Vertigo in parts of Europe, but Elektra is the standard U.S. label credit.

The label released the album under its official title, Metallica. “The Black Album” is an informal name derived from the nearly black artwork and is not the title printed as the album's formal name.

Elektra's release campaign supported a record that eventually produced five commercial singles: “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” “Wherever I May Roam,” and “Sad but True.” The album became the band's best-selling studio release.
