Morbid Angel is an American death metal band based in Tampa, Florida. They, along with Death, Possessed, Obituary, Deicide, Massacre, Cannibal Corpse, and a handful of others were crucial in the development of the death metal genre and its standards, seperating it from the thrash metal genre completely. 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". The band's songs are complex in arrangement, owing to the considerable technical skills of both Azagthoth and drummer Pete Sandoval (who also played in the grindcore/death metal band Terrorizer).
