Terrorizer is a death metal/grindcore band formed in 1986 in Los Angeles, California, United States. After disbanding in 1989, its members gained recognition as members of other influential extreme metal bands, such as Morbid Angel (David Vincent, Pete Sandoval) and Napalm Death (Jesse Pintado).
The group released their first album "World Downfall" in 1989. This album is considered immensely influential by many extreme metal aficionados. Then in 2003 an album containing two rehearsal sessions of the band from 1987 was released.
