Death metal
Death metal is a form of extreme metal that is generally distinguished by low-tuned guitar, low-pitched death grunt vocals, blast beats and erratic tempo and time signature changes. Lyrics typically revolve around themes of death, gore and violence, although some bands also address non-violent themes.
Death metal is an offshoot of thrash metal and the style was pioneered by the band Possessed in the mid-1980s. Since then death metal diversified spawning a rich variety of subgenres.
Other American bands such as Death, Morbid Angel and Cannibal Corpse subsequently adopted the format and developed it into a distinct genre.
