Choronzon is an industrial/black metal project from Winter Park, Florida, USA.

NOTE: Choronzon began as two separate and entirely unrelated bands with the same name: the eastern Choronzon was a Florida based black metal-styled band formed in 1986 by P. Emerson Williams, while its western counterpart Choronzon (aka Choronzon (9)) was the San Francisco old school industrial project of Demitria Monde Thraam formed in 1989.
In 2002, the two respective Choronzons became aware of each other via the internet, and agreed to share use of the name. Then, they decided to go even further and collaborate musically since 2004.

Prior to the merging of Choronzons, the East Coast Choronzon released of a series of self produced cassettes before being signed to the record label Nocturnal Art Productions in 1998, and then released the album "Magog Agog". Three more albums followed, in which the sound moved further away from conventional black metal into industrial and experimental territories. The first release from the conjoined Choronzon was the double album "" in 2005. All recording was completed mere hours before Hurricane Katrina made landfall.

The current lineup of Choronzon is P. Emerson Williams (Guitars, Bass, Vocals), Demitria Monde Thraam (Software synthesizers, effects and samples, Vocals), and the xenodimensional entity for which the project is named, CHORONZON, the force of which is a current that guides each of the two individual 'cells' and connects them during the real-time occult magick ritual effectuations that the albums are soundtracks for and documentations of.
