Fear Factory were formed in 1989 in Los Angeles by Dino Cazares (guitar), Raymond Herrera (drums), Burton C. Bell (vocals) and later Christian Olde Wolbers (bass) under the name Ulceration before switching in 1990 to their current moniker. 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. 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.
