Fear Factory is an American heavy metal band. Formed in 1989, they have released seven full-length albums and a number of singles and remixes. Over the course of their career they have evolved from a succession of styles, as well as steadily pioneered a combination of the styles death metal, groove metal, thrash metal and industrial metal. The resultant sound proved to be enormously influential on the metal scene from the mid-90s and onwards.
Fear Factory disbanded in March 2002 following some internal disputes, but they reformed later that year minus founding member Dino Cazares, adding bassist Byron Stroud, and casting then-bassist Christian Olde Wolbers as guitarist.
In April 2009, a new lineup was announced with founding guitarist Cazares returning, and Gene Hoglan being added as drummer. Bell and Stroud are both reprising their respective roles, and the band had completed a seventh studio album, Mechanize. Former members Christian Olde Wolbers and Raymond Herrera (both currently playing in Arkaea) dispute the legitimacy of the new lineup, and a legal battle is underway from both parties.
The band has performed at three Ozzfests as well as the inaugural Gigantour and has had singles in the US Mainstream Rock Top 40 and albums in the Billboard Top 40, 100 and 200. Prior to 2001 they have toured around 2000 shows. They have sold over 1 million albums in the US alone.
