Fear Factory is an American metal band, formed in 1990. Over the course of their career, the band has released eight full-length albums, and have evolved from a succession of styles, frequenting industrial metal with flavors of death metal, groove metal, and thrash metal. Fear Factory proved to be enormously influential on the metal scene in the mid- to late-1990s. Fear Factory disbanded in March 2002 following some internal disputes, but reformed later that year without founding member Dino Cazares, adding bassist Byron Stroud, and casting then-bassist Christian Olde Wolbers as guitarist.
