Anger and the tensions within the band during that time. A film titled Some Kind of Monster documented the recording process of St. Anger (2003) alienated many fans with the exclusion of guitar solos and the "steel-sounding" snare drum. Despite reaching number one on the Billboard 200, the release of St. A settlement was reached, and Napster became a pay-to-use service. In 2000, Metallica was among a number of artists who filed a lawsuit against Napster for sharing the band's copyright-protected material for free without any band member's consent. With this release the band expanded its musical direction resulting in an album that appealed to a more mainstream audience. Metallica achieved substantial commercial success with their eponymous fifth album (also known as The Black Album), which debuted at number one on the Billboard 200. The band earned a growing fan-base in the underground music community and critical acclaim with its first four albums, with their third, Master of Puppets (1986), described as one of the most influential and "heavy" thrash metal albums. The band also had a long collaboration with producer Bob Rock, who produced all of its albums from 1990 to 2003 and served as a temporary bassist between the departure of Newsted and the hiring of Trujillo.

Previous members of the band are lead guitarist Dave Mustaine, who went on to found Megadeth, and bassists Ron McGovney (demos only), Cliff Burton (the first three records, died in 1986), and Jason Newsted. The current line-up features founders Hetfield (vocals, rhythm guitar) and Ulrich (drums), longtime lead guitarist Kirk Hammett and bassist Robert Trujillo since 2003. Metallica formed in 1981 when James Hetfield responded to an advertisement that drummer Lars Ulrich had posted in a local newspaper. The band's fast tempos, instrumentals, and aggressive musicianship placed them as one of the founding "big four" of thrash metal alongside Slayer, Megadeth, and Anthrax. Metallica is an American heavy metal band from Los Angeles, California.
