Morbid Angel is an American death metal band based in Tampa, Florida, formed in 1983 by guitarist, primary composer and sole remaining original member Trey Azagthoth, vocalist and bassist Dallas Ward, and drummer Mike Browning. Widely considered one of the most influential bands in the genre and important in the transition of death metal from its thrash metal roots, they were one of the first bands to incorporate guttural vocals, up-tempo blast beats, multiple tempo changes and a dark atmosphere. They have been described as one of "the most influential and emulated bands in death metal", alongside Obituary, Death, Cynic, Autopsy and Deicide, and have been cited as an influence by many later bands. They were also the first death metal band to experience mainstream success in connection with being signed to Giant Records in 1992, heavy rotation of their music videos on MTV, and having the music video for the song "God of Emptiness" shown on an episode of Beavis and Butt-Head. Their first three albums – Altars of Madness (1989), Blessed Are the Sick (1991), and Covenant (1993) – are considered classics in the death metal genre.
