Have you heard of the Black Twilight Circle? Pretty much all of the bands that I mentioned are related to the scene and share members. Volahn (the musician) is involved in probably most of them. A number of the musicians, if I understand, are of Mexican heritage, so a few of the bands (particularly BHOTL and Kuxan Suum) incorporate some 'tribal' elements, for lack of a better word, but for the most part it's very raw and lo-fi straight ahead tremelo-driven black metal. Muknal and The Haunting Presence have a lot more death metal influence, whereas Axeman is hard to really classify as black metal at all. They're more of a crust/thrash/death metal band that takes a lot of cues from Amebix.
The Black Twilight Circle and the Crepusculo Negro label rightfully have a shitty reputation, but once I looked past a lot of the silliness that I read about them, I found that a lot of the music that they actually put out I found to be quite rewarding. I think the 'scene' is kind of dead at this point, but there's another, seemingly more responsible label called Rhinocervs (which originally released the Tukaaria and Odz Manouk albums) that seems to pick up a bit where they left off. The label is owned by two musicians in the scene, I believe, but I don't know who. They release collaborative recordings under the label's name on untitled tapes. I've heard excellent things about these tapes, but I haven't heard any of them myself.
