Operating out of the wastelands of Southern Ontario, Promonium Jesters play psychedelic industrial thrash music, incorporating elements of metal, noise, ambient, trance, and digital hardcore with a heavy emphasis on experimentation.

Promonium Jesters were formed by Ethan Moseley and Greg Cox in 1995 in Uxbridge, Ontario, Canada. Since that time the band has recorded and released 11 albums through their own label, P in a Circle Records.

The band has been performing live around the Toronto area since 1996, but it wasn’t until the release of Your Face in 2007 that Promonium Jesters embarked on their first cross Canada tour. This was followed by another cross Canada tour in May 2008 to promote Psychic Warfare, with Thunder Bay’s own Adaptive Reaction as a supporting act.

A Promonium Jesters performance is a multimedia event, as the band utilizes a custom built home made light show, as well as a multiple video projector set up show videos made by the band. To date, Promonium Jesters have shared the stage with a diverse range of performers such as Left Spine Down, Cyanotic, The Kettle Black, and Merzbow.

Promonium Jesters have recently released a split 7" with Adaptive Reaction. Both bands are currently booking a cross Canada tour to take place in September/October 2009, that will coincide with the release of the next Promonium Jesters full length album.
