Fear Factory were one of the first bands to fuse the loud, crushing intensity of death metal with the cold harshness of industrial electronics and samples, producing a more varied sonic palette with which to express their bleak, pessimistic view of modern, technology-driven society. The group was formed in Los Angeles in 1990 by vocalist Burton C. Bell (formerly of Hate Face), percussionist Raymond Herrera, and guitarist and ex-Douche Lord Dino Cazares. Following their contribution of two tracks to the L.A. Death Metal compilation, Fear Factory signed to Roadrunner Records and released their debut album, Soul of a New Machine, in 1992, which featured new bass player Andrew Shives, added to allow Cazares to play guitar on tour. The following year's Fear Is the Mind Killer EP showed Fear Factory's willingness to experiment with their music and broaden its scope by placing tracks from their debut in the hands of remixers Rhys Fulber and Bill Leeb of Front Line Assembly; the EP also marked the debut of keyboardist Reynor Diego, who along with Fulber joined the band as a touring keyboardist. Shives was fired in 1994 and replaced by Christian Olde Wolbers.
