Terrorizer is an American deathgrind band from Los Angeles, California. It was originally formed in 1985 as Unknown Death by vocalist Oscar Garcia and guitarist Jesse Pintado. They would rename themselves Terrorizer after recruiting drummer Pete Sandoval, who remains the band's sole constant member throughout their discography, in 1986. The band's current lineup consists of Sandoval, bassist David Vincent, vocalist Brian Werner and guitarist Richie Brown. They are currently signed to Earache Records.

Hellhammer was a Swiss extreme metal band from Nürensdorf, active from 1982 to 1984. Although the band's sound and style were heavily criticized and poorly reviewed during their active years, they have been widely praised in retrospect and are often regarded as a key influence on black metal. In June 1984, Hellhammer disbanded but two of its members soon formed the influential extreme metal band Celtic Frost.
