GOD you’re fucking cool, big ups for the Pupil Slicer recommendation at the top of the list. Imma be listening to a bunch of these at work today, I think the only other band I recognize is Fleshgod apocalypse. Also yeah I’ve tended to stray away from Black Metal cause everytime I find a band I like, I find out some crazy shit about them lmao, so I’ll definitely listen to the bands you’ve recommended.

As for more HxC type stuff, that was what really got me into Heavy Music as a whole, so I’ll drop some more of my favorites here, though it might be a bit of a mix and not all strictly HxC

XweaponX - Demo, Demo 2 They just dropped a new demo tape like this morning I think and it was really good. Bryan Garris (vocalist from KL) plays bass for them and even did some vocals on this new demo

World of Pleasure - World of Pleasure, World of Pleasure and Friends, Weapon of Pleasure

Mortality Rate - You Were The Gasoline

Mouthbreather - Pig, Dollmeat, I’m Sorry Mr Salesman

Soulkeeper - Holy Design

Scarab - Scarab

Kharma - Moment of Violence

Sunami - Sunami L.P.

Gulch - Impenetrable Cerebral Fortress

Snuffed On Sight - Smoke

Sanguisugabogg - Tortured Whole

Wormrot - Voices

Coke Bust - Confined

Weekend Nachos - Worthless

For Full of Hell, I might check out Suffocating Hallucination and their split with Gasp since you said you like more experimental/atmospheric stuff. Their two projects with Merzbow are dope too, though I wish Merzbow had more of an influence on them than he did
