Nocturnus was formed in 1987 by former Morbid Angel drummer Mike Browning. The band, as were many others, was formed in Tampa, FL. Nocturnus’ songs are typically subjects of science-fiction, and uses keyboards more than most Death Metal bands. The band has undergone many lineup changes throughout the years.

While Nocturnus remains relatively obscure (even for Death Metal), Necrophagist and Children of Bodom both cite the band as an influence.
