Theurgion are a new doom metal entity featuring members involved in bands such as Chaos Moon, Krieg, Häxanu, Azelisassath, Kveldstimer, and Collier d'Ombre (just to name a few of the many projects the three members of this band are involved in). Theurgion play towering and melancholic death-via-traditional doom metal. All Under Heaven is comprised of seven sculptured sonic monuments that hail those that came before (Solitude Aeturnus, mid-era Bathory, old Katatonia, old Anathema, first October Tide LP etc.) while carving it's solitary monolith to merge itself in the new age.
