Influenced by British Grindcore and extreme music such as Napalm Death and Godflesh, Fear Factory's career has seen them pioneer a hybrid of Death Metal, Industrial Metal, Alternative Metal and electronic music.
Their first album "Concrete" from 1991 was not released until 2002. This was also the first production job for then unknown Ross Robinson who would later produce bands such as Korn, Machine Head, and Slipknot.
Strong personal differences led to a break-up in 2002 but the band re-formed a year later minus Cazares with bassist Christian Olde Wolbers taking on guitar duties while Strapping Young Lad's Byron Stroud entered to take over live bass. Another hiatus followed in 2006.
In 2009 Fear Factory returned with founding member Cazares in the band again, but without Herrera and Wolbers.
