Karloff

Based on the releases you've listed, this appears to be Karloff, a raw black metal band from Sweden.

Formed in the 2010s, Karloff is known for its uncompromising, lo-fi, and atmospheric take on the black metal genre. The band has cultivated a dedicated following within the underground scene by consistently releasing cassette tapes, vinyl, and digital albums—titles like "Revered by Death" and "Crown Kvlt Fate" are quintessential of their style, which often blends harsh, minimalist production with a sense of grim melody and relentless pace. They embody the DIY and kvlt spirit, often shrouded in the typical anonymity of the genre, letting their prolific stream of raw, frostbitten music speak for itself.
