Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted guitars, tremolo picking, deep growling vocals, blast beat drumming, minor keys or atonality, and complex song structures with multiple tempo changes.

Building from the musical structure of thrash metal and early black metal, death metal emerged during the mid 1980s. Metal acts such as Slayer,Kreator,Celtic Frost, and Venom were very important influences to the crafting of the genre.Possessed and Death, along with bands such as Obituary, Carcass, Deicide and Morbid Angel are often considered pioneers of the genre. In the late 1980s and early 1990s, death metal gained more media attention as popular genre niche record labels like Combat, Earache and Roadrunner began to sign death metal bands at a rapid rate. Since then, death metal has diversified, spawning a variety of subgenres.

English heavy metal band Venom, from Newcastle, crystallized the elements of what later became known as thrash metal, death metal and black metal, with their 1981 album Welcome to Hell. Their dark, blistering sound, harsh vocals, and macabre, proudly Satanic imagery proved a major inspiration for extreme metal bands. Another highly influential band, Slayer, formed in 1981. Although the band was a thrash metal act, Slayer's music was more violent than their thrash contemporaries Metallica, Megadeth and Exodus. Their breakneck speed and instrumental prowess combined with lyrics about death, violence, war and Satanism won Slayer a rabid cult following. According to Allmusic, Slayer's third album Reign in Blood "inspired the entire death metal genre". It had a big impact on the genre leaders.

Death was an American metal band founded in 1983. The band's founder, Chuck Schuldiner, is considered "a pioneering force in death metal and grindcore". The band ceased to exist after Schuldiner died of brain cancer in 2001, though remains an enduring metal brand.

Death is considered one of the most influential bands in metal. The band's debut, Scream Bloody Gore, has been described as "death metal's first archetypal document" and "the first true death metal record". One music biographer has referred to Schuldiner as the "Father of Death Metal" while another has claimed that Schuldiner is "readily acknowledged as the true founder of the U.S. death metal scene".

As of 2008, Death had sold over 2 million albums worldwide, with over 500,000 copies sold by December 2009 in the U.S. alone (excluding the numerous sales before the SoundScan era) making them the top-selling death metal band worldwide, and only topped in the U.S. by Cannibal Corpse.

Founded in 1983 by Chuck Schuldiner under the original name of Mantas in Orlando, Death was among the more widely known, early pioneers of the death metal sound along with California's Possessed. In the late 80s, the band was both a part of and integral in defining the death metal scene which gained international recognition with the release of albums by a number of area acts.
