Morbid Angel is an American death metal band based in Tampa, Florida. UK music magazine Terrorizer ranked two Morbid Angel albums in its "Top 40 Greatest Death Metal Albums," with their 1989 debut Altars of Madness appearing at number 1. Decibel Magazine also rated guitarist Trey Azagthoth as the number 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). According to Nielsen SoundScan, Morbid Angel is the third best-selling death metal band in the United States with sales over 445,000[1] in the United States alone, with their third album Covenant being the best-selling death metal album of all time in the United States, at over 127,000 units sold.
