The  death metal  is an extreme sub-genre of heavy metal. It usually uses very distorted guitars,  tremolo picking , growlingprofonds,  blast beats , minor scales and complex structures with multiple tempo changes.

It was in early 1980 that the death metal emerged, first in the form of a thrash metal more complex and violent  2 . Metal bands such as Slayer 5 , Kreator 6 , Celtic Frost 7  and Venom have been very important influences for pioneers of genre 2 . Possessed 8  and Death 10 11  with groups like Obituary, Master, Atheist or Morbid Angel are often considered pioneers of the genre 12. In the 1980s and early 1990s, death metal gained more media attention thanks to popular labels like Combat, Earache and Roadrunner who began to sign death metal bands at a rapid pace 13 . Since then, death metal has diversified, producing a variety of subgenres 14 .

There are several versions as to the “real” origins   of death metal. Some cite the Possessed group as the first of its kind. This version is denied by others, who nevertheless believe that Possessed remains the first group of thrash / death metal with death metal sounds, and that it will influence the extreme metal groups to come. Mantas, Death Strike, Ravage, Genocide and Executioner (which will become Death, Master, Atheist, Repulsion and Obituary), which recorded several demos between 1983 and 1984, followed by Morbid Angel In 1983 but later recorded (the first demo dates from 1986) and Amon which is formed in 1987. The tape  Death Metal Of Possessed, released in 1984, will play an important role in the creation of this style (hence the origin of the name of this musical style), directly influencing Chuck Schuldiner, who changes the name of his group Mantas in Death, Other groups like Executioner.

The albums Leprosy by Death, Altars of Madness by Morbid Angel and Slowly We Rot by Obituary are considered the first albums that gave definitions to classic death metal. Major influential groups include: Cannibal Corpse, Death, Dismember, Deicide, Entombed, Gojira, Benediction, Morbid Angel, Obituary, Suffocation, and Vader.

The origin of the term  “death metal”  is relatively vague. There are several groups or individuals to whom the first use of the term is assigned. The band Mantas (future Death) releases a demo in 1984 called  Death by Metal 15 , the name of the group may also have inspired the name of the movement [ref. Required] . Also released in 1984, the demo of Possessed simply called  Death Metal . In the UK, the thrash metal band Onslaught had a song on their debut album entitled  Death Metal . Because of the repeated use of this term, a compilation released in 1984 called  Death Metal Groups such as Helloween or Hellhammer. Although it is agreed that the Death group has the paternity of death metal, we also note in the precursors of the genre two other formations: Morbid Angel and Possessed, both founded in 1983, and played a role as important as the Group of Chuck Schuldiner in the expansion of this kind.
