Using the Waldorf PPG Waveterm-A sound systems that made Tangerine Dream and Kraftwerk most famous, the darkwave outfit Xorcist joined the reign of fellow industrialists like Skinny Puppy, Frontline Assembly, and Nitzer Ebb with its inception in 1985. Composed of Bat, Xorcist became a forerunner in the electro-goth circuit throughout the '80s and '90s, releasing six albums and a handful of singles between 1991 and 1999. What made Xorcist so popular was the incredible mixing of various industrial and goth rock threads; the music couldn't be wholly defined. Bat also delved into a side project called Xenon and went on to have some of his material sampled in several films and multimedia productions, most notably working production on MTV's Aeon Flux and the CD-ROM games !The Iron Helix, !Space Bunnies Must Die, and !Bad Mojo. Xorcist, who was signed to Metropolis as of early 2000, released Insects & Angels Difference & Indifference later that fall. Xorcist's album roster also includes Phantoms (1995), Soul Refelection (1997), and Nomad (1999). (MacKenzie Wilson, All Music Guide.)

Xorcist started as a one-man act, founded by Bat who began experimenting in music in 1985. In 1990, he formed Xorcist in an attempt to set new musical standards in the electronic music scene, crossing over industrial music with sonic soundscapes. He was eventually joined by Evoltwin.8, who also provided cover art for several releases.

As of recently, all music released by Xorcist as well as Stone's other projects (Xenon and Diode Fetish) are available for download on the official website. Bat continues to DJ under the name DJ Bat, and hosts his own radio show on his website: CyberDen. Bat has also done work on the MTV production Aeon Flux, as well as the soundtracks for the games The Iron Helix, Bad Mojo, and Space Bunnies Must Die. (Wikipedia.)
