Detroit-based industrial-metal musician Klayton (born Scott Albert) started his most well-known project, Celldweller, in 1999 following the dissolution of his previous bands Circle of Dust, Angeldust, and Argyle Park. Celldweller's self-titled debut album, an ambitious fusion of trance, drum'n'bass, metal, and alternative rock, appeared in 2003 on Position Music/Esion Media after four years of production and delays. The album was well-received by various online music communities, and eventually every song from the album was licensed to television shows, motion pictures, or video games. The Beta Cessions, a double CD of remixes, demo versions, and instrumentals, followed in 2004.
In 2006, Klayton started independent label FiXT Music, which would release all of his subsequent recordings, as well as releases by other artists. While working on Celldweller's second proper full-length Wish Upon a Blackstar, Klayton began Take It and Break It, a competition in which fans could remix Celldweller songs. The competition spawned several volumes of remix collections which were released on FiXT. Soundtrack for the Voices in My Head, Vol. 1, an instrumental album intended for further media licensing, was released in 2008. Klayton began digitally releasing tracks from Wish Upon a Blackstar in 2009 in the form of two-song "chapters." He also began recording Soundtrack for the Voices in My Head, Vol. 2, releasing the first chapter in 2010. Remix album The Complete Cellout, Vol. 1 appeared in 2011. Both Wish Upon a Blackstar and Soundtrack for the Voices in My Head, Vol. 2 finally saw full release in 2012, as well as concert recording Live Upon a Blackstar, also released as a Blu-Ray/DVD. By this time, Celldweller's sound had evolved to include elements of dubstep, and was referred to as "metalstep."
Celldweller's self-titled debut was given a 10th anniversary deluxe reissue in 2013, and Klayton began working on the next proper Celldweller album, End of an Empire, as well as Soundtrack for the Voices in My Head, Vol. 3. The first two chapters of End of an Empire, both full-length compilations with numerous remixes and instrumentals, were released in 2014, as well as compilation Transmissions, Vol. 1. The third chapter of End of an Empire appeared in 2015, along with Transmissions, Vol. 2. ~ Paul Simpson, Rovi
