my favorite band is metallica.
[{"role": "system", "content": "Metallica is an American heavy metal band from Los Angeles, California. The band was formed in 1981 by drummer Lars Ulrich and vocalist/guitarist James Hetfield. 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 Hetfield and Ulrich, longtime lead guitarist Kirk Hammett and bassist Robert Trujillo. Guitarist Dave Mustaine (who formed Megadeth) and bassists Ron McGovney, Cliff Burton and Jason Newsted are former members of the band. Metallica earned a growing fan base in the underground music community and won critical acclaim with its first five albums. The band's third album, \"Master of Puppets\" (1986), was described as one of the heaviest and most influential thrash metal albums; its eponymous fifth album, \"Metallica\" (1991), the band's first to root predominantly in heavy metal, appealed to a more mainstream audience, achieving substantial commercial success and selling over 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, the band returned to its thrash metal roots with the release of its ninth album, \"Death Magnetic\" (2008), which drew similar praise to that of the band's earlier albums.\n"}, {"role": "user", "content": "Metallica is probably my favorite band.
