Formed in Los Angeles, California, USA, in 1994, Coal Chamber are led by gruff vocalist Dez Fafara and operate in territory somewhere between the traditional hard riffing of Black Sabbath and the sensationalist techno rock of Marilyn Manson. Fafara met guitarist Miguel "Meegs' Rascon through a classified ad, and they later added drummer Mike Cox and bass player Rayna Foss, the room-mate of Fafara's future wife. They signed to Roadrunner Records in 1995 after being recommended by Dino Cazares of Fear Factory, and received widespread exposure in the metal press as that label's hottest new property since Machine Head. Their debut attained further strong reviews, despite having been recorded under stressful conditions - on the day recording started, Fafara's wife left him. An already intimidating suite of songs was thus transformed into something of a personal exorcism. Having previously toured with Danzig, they also supported labelmates Machine Head on their 1997 UK tour. Their sophomore set, 1999"s Chamber Music, was boosted by the inclusion of their highly popular cover version of Peter Gabriel's "Shock The Monkey", featuring Ozzy Osbourne on vocals. Foss, who gave birth to her daughter by Morgan Rose of Sevendust the same year, was temporarily replaced by Nadja Peulen. The arrangement became permanent in 2002. The band was further unsettled when Cox departed the same September.
