The most well-known Katharsis is a German raw / orthodox black metal band in the vein of Darkthrone, but with added layers of complexity and strangeness. The members are M.K. on "styx" (drums), Scorn on "scythe" (guitar), and Drakh doing "sting" (vocals).

The group does not play live shows / tour. Some of their recent t-shirts were released by NED (www.noevdia.com).

Katharsis has released three full-lengths to date: one via Sombre (2000's "666" LP only, later re-released by NOEVDIA on CD), two via Norma Evangelium Diaboli aka NED aka NOEVDIA (2003's "Kruzifixxion" and 2006's "VVorldVVithoutEnd").

They were supposed to release a split with Antaeus in 2007, but it was unfortunately cancelled due to Antaeus' line-up problems.

Katharsis has also participated in split releases with Moonblood, Deathcult (GER), Nhaavah and Black Witchery. Compilations they appear on include: Black Metal Endsieg I (2001), Black Metal Blitzkrieg (2001), Tormenting Legends II (2006).

There also exists a bootleg titled "Kommando Metal", which contains the following demos:

Into Endless Chaos Demo, 1997
The Red Eye of Wrath Demo, 1998
Trident Trinity Split, 1999
