A death metal act from Newhall, California active since 2012, Montezuma operate in the Los Angeles underground with the punishing directness the genre requires — heavy, methodical, and uninterested in subtlety.

Their music reaches for panoramic scale — sweeping melodic passages and vast, reverb-drenched tremolo that evoke the grandiose landscapes of the genre's most cinematic practitioners.

Moon Twin is a Corona, California experimental death metal project formed in 2017, pushing the genre's boundaries through unconventional song structures and a willingness to absorb influences from outside metal entirely.

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. The dungeon synth dimension sets them apart from pure raw black metal acts, suggesting a project as interested in solitary introspection as in harsh noise.
