Ildjarn is the solo project of Vidar Vaaer, former bassist of Death Metal band Thou Shalt Suffer (which later turned into Emperor). During 1992-1996 Ildjarn (occasionally collaborating with fellow Norwegians Nidhogg and Ihsahn) recorded various demos, 7"s and albums containing extreme, harshly distorted, raw metal interspersed with minimalist ambient soundscapes, and disappeared from public view shortly after the release of "Landscapes", a double album containing nothing but droning ambient pieces. In 2002 Ildjarn returned with two ambient releases "Hardangervidda", recorded in collaboration with Nidhogg.
