Way too wide description and including too many different things (basically everything from Nekrophile Rekords tapes to Vinterriket coming across Burzum ambient records, Mortiis, etc..), but still interesting macro-container of evil black metal inspired music, not played with metal equipment though.
I didn´t see them named in this topic so I throw my 2 cents on the table with some French projects which came out for black metal labels around 15 years ago like Dapnom, Nommam Erytz, Taog Susej etc..minimal satanic death industrial with a lot of creepy, disturbing and evil atmospheres.
