Moonlantern is a San Diego raw black metal and dungeon synth project formed in 2018, occupying the atmospheric, lo-fi end of the underground where raw black metal and ambient synth work share the same physical and spiritual space.

One of the longer-running black metal acts in Southern California, Santa Ana's Mordor have maintained their dark vision since 1994 — an impressive run for the Los Angeles area underground.

Oakland's Morgana work in the post-black metal space, tempering the genre's harshness with expansive, emotionally resonant passages that reflect the Bay Area's experimental underground ethos since 2020. Their music moves between abrasion and melancholy with a fluidity that suits their Arthurian name's associations with mystery and transformation.

Oakland's Morir merge black metal's corrosive atmosphere with the grinding physicality of sludge metal and hardcore punk, formed in 2018 and operating in the Bay Area's restlessly genre-crossing underground heavy music community.
