Metallica
is an American heavy metal band from Los Angeles, California. 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 formed in 1981 when James Hetfield responded to an advertisement that drummer Lars Ulrich had posted in a local newspaper. As of 2003, the line-up features long-time lead guitarist Kirk Hammett (who joined the band in 1983) and bassist Robert Trujillo (a member since 2003) alongside Hetfield and Ulrich. Previous members of the band are lead guitarist Dave Mustaine (who went on to found the band Megadeth), and bassists Ron McGovney, Cliff Burton and Jason Newsted. 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.

Megadeth
is an American heavy metal band from Los Angeles, California, that was formed in 1983 by Dave Mustaine and David Ellefson. The band has since released 13 studio albums. A pioneer of the American thrash metal movement, Megadeth rose to international fame in the 1980s and is ranked as one of the "Big Four of Thrash" along with Metallica, Slayer and Anthrax, who were responsible for creating, developing and popularizing the thrash metal sub-genre. Over the band's 30 active years, more than 20 different people have officially performed as part of the group, with Mustaine being the only constant member. Megadeth is known for its distinctive, technical instrumental style that often features dense, intricate passages and trade-off guitar solos, and for recurring lyrical themes including politics, war, addiction, personal relationships, and religion. The band has sold over 50 million records worldwide with six consecutive albums being certified platinum or multi-platinum in the US, according to the band's official website. Peace Sells... but Who's Buying?, So Far, So Good... So What!, Rust in Peace, Youthanasia, and Cryptic Writings all achieved platinum status, the band's fifth and most successful record, Countdown to Extinction, sold multi-platinum, and the album Risk achieved gold certification. As of 2013, Megadeth has received eleven Grammy nominations.

Slayer
is an American thrash metal band formed in Huntington Park, California in 1981 by guitarists Kerry King and Jeff Hanneman. Slayer rose to mainstream fame with their 1986 release Reign in Blood, and is credited as one of the "Big Four" thrash metal acts, along with Metallica, Megadeth and Anthrax. Slayer's sales are in the estimated high 20 millions, although they have never publicly announced their sales worldwide. However, between the years 1991 and 2004, Slayer sold over 3.5 million albums in the U.S. Slayer's musical style involve fast tremolo picking, double bass drumming, and shouted vocals. King, bassist/vocalist Tom Araya, and former guitarist Jeff Hanneman have contributed to the band's lyrics. Most of the band's music has been created and arranged by King and Hanneman, with additional help from drummer Dave Lombardo and sometimes Araya. The band's lyrics and album art, which cover topics such as serial killers, necrophilia, Satanism, religion, anti-religion, and warfare, have generated album bans, delays, lawsuits and criticism from religious groups and the public. Their music has been highly influential, often being cited by many bands as an influence musically, visually, and lyrically.

Anthrax
is an American thrash metal band from New York City, New York, United States, formed in 1981. Founded by guitarists Scott Ian and Danny Lilker, the band has since released ten studio albums and 20 singles, and an EP featuring American hip hop group Public Enemy. The band was one of the most popular of the 1980s thrash metal scene. When thrash metal began to gain a major following in the mid-to-late 1980s, Anthrax were dubbed one of the "big four" of thrash metal alongside Metallica, Megadeth and Slayer.
They were also one of the early thrash metal bands to sign to a major label (Island Records, in 1985). As of 2004, Anthrax sold over 2.5 million records in the U.S since the beginning of the SoundScan era[7] and as of 2012, they have sold over 15 million records worldwide. The band line-up has been changed numerous times; following the departure of drummer Dave Weiss and bassist Kenny Kushner, several musicians replaced both band members' roles, though Paul Kahn and Greg Walls were the first to do so. In addition to this aspect, there were multiple vocalists involved in Anthrax, with Neil Turbin, Joey Belladonna and John Bush being among the frontmen of the band. Scott Ian, however, has been in the band since its formation. Ian and Charlie Benante, who joined Anthrax in 1983, are the only constant members that appear on every album. Bassist Frank Bello has played on every album with exception of the band's debut. Classic singer Joey Belladonna has returned to the band and appears on Worship Music, which is his first studio album with the band since 1990's Persistence of Time.
