There are three bands of the same name. 1: Abhorrence was a Finnish death metal band formed in 1989. The band was active only for one year. They released the famous "Vulgar Necrolatry" demo tape, that was in heavy circulation all the way to mid 90’s underground scene. The demo was followed by a self-titled EP, which was recorded for Seraphic Decay records, infamous for ripping off the bands whose music they released. The band featured guitarist Tomi Koivusaari who would go on to form Amorphis.
