In 2003, Bolt recorded its first full length effort, "Circadian Rhythm," a raw and energetic work with tinges of video game music peeking out from behind relentless and raucous riffage. Bolt independently released the record in March of 2003 whereupon the band continued to play and record but consciously initiated somewhat of a musical shift.

Captivating and unique, Bolt?s noticeably darker sophomore release, "Movement and Detail", has a personality that is indeed hard to pin down. There?s a self-effacing thread that runs throughout the entire album, just beneath the cool technical precision. The band shifts from eerie atmospherics to hints of jazz but also sashays from metal riffage to downright dance-able texturing that forces you to do the tango, again, and again.
