Also check some Stallaggh stuff, Abruptum (not industrial, but early stuff has a very sick feeling, not far from industrial approach), Thorns (very cold, almost surgical atmophere),Nyogthaeblisz, Khel, Yhdarl (or almost anything from Deha), old Axis of Perdition, Tele S Therion, Black Funeral..and maybe later i can recall of some else bands and projects.
