Entombed is a Swedish death metal band formed in 1987 as Nihilist. Entombed began their career as an early pioneer of Scandinavian death metal, which differed from its American counterpart by its distinct "buzzsaw" guitar tone. Their sound evolved by the early-to-mid-1990s and the band began to explore progressive, punk, hard rock, garage rock, and groove metal influences, which shaped the sound of death 'n' roll. Along with Dismember, Grave and Unleashed, Entombed has been referred to as one of the "big four" of Swedish death metal.
