Fear Factory in Boise

Fear Factory is an American industrial-metal band formed in Los Angeles in 1989. Their music pairs tightly synchronized guitar riffs and drums with electronic textures and a contrast between harsh and clean vocals. The albums Demanufacture and Obsolete established that sound through songs including “Replica,” “Shock” and “Edgecrusher,” while “Linchpin” became a key track from Digimortal. Fear Factory joined Iron Maiden’s The X Factour in 1995 and played the first Ozzfest the following year. In 2005, they toured on the inaugural Gigantour, whose lineup also included Megadeth, Dream Theater and Anthrax.

Darkest Hour is an American metal band formed in Washington, D.C., in 1995. Their music draws on melodic death metal, metalcore and hardcore, and they are known for albums including Undoing Ruin and Deliver Us, as well as songs such as “Convalescence” and “Demon(s).” Darkest Hour performed on Ozzfest in 2004 and joined The Sounds of the Underground tour the following year. They later supported At the Gates on the Swedish band’s 2008 North American reunion tour, extending a live history built through club shows and major touring packages with At the Gates.
