Arkaea is an industrial metal supergroup formed in 2008 featuring members from Threat Signal and Fear Factory. The band was formed by Christian Olde Wolbers and Raymond Herrera (formerly of Fear Factory) who had recorded a demo for a new band. They sent the demo to Threat Signal vocalist Jon Howard and Arkaea was spawned. They tried to obtain Sam Rivers of Limp Bizkit for bassist, who was all for it but then decided to back down due to location.
