UPDATED:
Groups like Venom, Mercyful Fate, and Slayer may have founded death metal in the early '80s, but it wasn't until such disciples as Morbid Angel came along at the close of the decade that the genre was pushed to its most extreme level, both musically and lyrically. Formed in 1984 in Florida, Morbid Angel (along with Death) would also help spearhead an eventual death metal movement in their home state. In 1989 they released "Altars of Madness" and 1991's "Blessed Are the Sick" is considered by many as a landmark release in the death metal genre.
