THRONE OF KATARSIS was spawned in 2003 in Norway by the demonic visions of Grimnisse and Vardalv. Their prophecy was and still is to craft purified and atmospheric occult Black Metal in the true vein of the early 90-ties Norwegian Black Metal, and focused on spreading the unholy message through their blasphemous lyrics. Their line-up is simple, yet effective: Vardalv - battery, Grimnisse - the rest.

March 2004 the now infamous demo recording entitled Unholy Holocaustwinds was unleashed upon the world. There were initially only released 40 copies of the demo, but after massive unforeseen response and requests the demo has been re-released on pro-printed MC and 10" LP by German Warfront Production and on CD by UK based Paradigms Recordings. Unholy Holocaustwinds was recorded on a four-track cassette recorder, partly in the Liarlund Forest.

Late 2004, accompanied by two session-musicians on bass and guitar, THRONE OF KATARSIS did their first live performance at John Dee, Oslo, Norway.

Apart from a live gig at the Karmøygeddon metal festival, THRONE OF KATARSIS spent 2005 focusing on recording their debut full-length. The recording process took place at Black Dimension Studio owned and operated by Stein Sund of Thundra.

In March 2007 the highly acclaimed debut album An Eternal Dark Horizon was released on Candlelight Records. The band did some concerts and festivals, and also a small European tour. Further more the band started the recording of their next opus, and Black Dimension Studio, Norway, was used once again. The true essence of Black Metal will be captured on tape and brought upon the masses in 2008.
