Metal Forces is a British publication founded in 1983 which promotes the music genres heavy metal and hard rock. Metal Forces was well known for its coverage of unsigned bands through its Demolition feature and championed the likes of Metallica, Slayer, Megadeth, HellsBelles, Overkill, Death and Poison long before they had secured record deals. They are credited as contributing in this fashion to the success of the band Anacrusis. Dave Reynolds, a former writer for Metal Forces, has claimed that the magazine was the first to coin the terms thrash metal and death metal. A Metal Forces compiled vinyl album, Demolition – Scream Your Brains Out!, based on the magazine's popular Demolition column, was released in 1988 through Chain Reaction Records featuring Anacrusis, Atrophy, Hobbs' Angel of Death, Aftermath and the Chris Barnes fronted Leviathan. In addition to metal acts, the magazine also featured interviews with alternative rock acts such as Nirvana.

Metallica is an American heavy metal band. The band was formed in 1981 in Los Angeles by vocalist and 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. Guitarist Dave Mustaine, who formed Megadeth after being fired from Metallica, and bassists Ron McGovney, Cliff Burton and Jason Newsted are former members of the band.
