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.
