Which record label released Metallica's 1991 self-titled album in the United States?

Elektra Records released Metallica's 1991 self-titled album in the United States.

The release followed Metallica's earlier relationship with Megaforce Records, the label associated with the band's debut album, Kill 'Em All. By the time of The Black Album, Metallica was established with Elektra, which had also released Ride the Lightning, Master of Puppets, and ...And Justice for All.

International editions involved other labels, including Vertigo Records in many territories. That difference can cause confusion when album discographies list more than one label for the same record. The U.S. edition is specifically identified with Elektra.

The album's commercial impact was enormous for both the band and its label. It became Metallica's first album to reach number one on the Billboard 200 and spent four consecutive weeks at the top. Its success helped move the group from metal prominence into worldwide mainstream stardom.
