The sound is based in electronics, but also wields an aggressive rock edge. The music will make you feel something, strike a chord inside, and also make you want to move. The music is well-crafted without being overly sterile or refined; it retains a raw energy missing in so much electronic-based music without losing a solid dancefloor feel. The lyrical themes include fear, confusion, self-doubt, and the flaws of modern society, but also defiance, self-discovery, and finding inner strength--the songs explore both the positive and the negative, rather than dwelling on only one or the other. The sound includes elements of industrial, elektro, metal, gothic, rock, and punk.
The band was formed in mid 2001. James (vocals, guitar, programming) and Jason (guitar, synth, programming) had previously worked together as members of San Francisco Bay Area future-metal stalwarts Spitkiss and the more gothic-leaning Dreams of the Fall. Corinne (bass, programming, graphic design) joined soon later. In December 2002, Dane (keyboard, programming) joined the band.
Control Theory ceased activity in mid-2004.
