Metallica

Metallica is an American heavy metal band. It was formed in Los Angeles in 1981 by vocalist/guitarist James Hetfield and drummer Lars Ulrich, and has been based in San Francisco for most of its career. The band's fast tempos, instrumentals and aggressive musicianship made them one of the founding "big four" bands of thrash metal, alongside Megadeth, Anthrax, and Slayer. Metallica's current lineup comprises founding members and primary songwriters Hetfield and Ulrich, longtime lead guitarist Kirk Hammett, and bassist Robert Trujillo. Former members of the band are bassists Ron McGovney, Cliff Burton, and Jason Newsted, and guitarist Dave Mustaine, who formed Megadeth after being fired from Metallica in 1983.

Metallica first found commercial success with the release of its third album, Master of Puppets (1986), which is often cited as one of the best metal albums of all time. The band's next album, ...And Justice for All (1988), gave Metallica its first Grammy Award nomination. Its fifth album, Metallica (1991), was a turning point for the band that saw it transition from its thrash metal roots; the album appealed to a more mainstream audience, achieving substantial commercial success and selling more than 16 million copies in the United States to date, making it the best-selling album of the SoundScan era. After experimenting with different genres and directions in subsequent releases, Metallica returned to its thrash metal roots with its ninth album, Death Magnetic (2008), which drew similar praise to that of the band's earlier albums. The band's eleventh and most recent album, 72 Seasons, was released in 2023.
