Morbid Angel is a Florida-based death metal band assembled in 1983. They, along with Deicide, Death, Possessed, Obituary, Massacre, Cannibal Corpse and a handful of others were crucial in the development of the death metal genre and its standards. UK music magazine Terrorizer ranked two Morbid Angel albums in its "Top 40 Greatest Death Metal Albums," with Altars of Madness appearing at #1. Decibel Magazine also rated guitarist Trey Azagthoth as the #1 "Death Metal Guitarist Ever." Their songs are complex in arrangement, owing to the considerable technical skills of Trey and drummer Pete Sandoval who also played in the grindcore/death metal band Terrorizer.
