Morbid Angel is a Tampa, Florida, United States-based death metal band assembled in 1984. They, along with Deicide, Death, Possessed, Autopsy, Suffocation, Obituary, Massacre and a handful of others were crucial in the development of the death metal genre and its standards. Their songs are complex in arrangement, owing to the considerable technical skills of both guitarist Trey Azagthoth and drummer Pete Sandoval (who also played in the grindcore/death metal band Terrorizer).
