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.

A Buffalo, New York heavy metal band formed in 2021, Monument began in the city's storied tradition of hard, guitar-driven music and have since evolved toward a harder rock sensibility while retaining their metal roots.

Oklahoma City's Monument started out in power metal territory before shifting into a more aggressive death/thrash hybrid, reflecting the kind of restless evolution that has defined the band across their existence since 2021.

Denver's Monumental Discharge formed in 2020 and specialize in slam and brutal death metal, delivering the genre's characteristically downtuned, bowel-shaking low end and guttural vocals against a backdrop of Mile High city extremity.

Mookerdam is a Los Angeles band dragging death metal into the swamp, combining crushing doom weight with sludge-coated riffs and an abyssal low-end that has been their signature since forming in 2010. The band occupies the uglier, slower end of the death-doom spectrum, where tempo is a weapon and density is the point.

Moon Drunk is a Chicago trio formed in 2021 colliding grindcore velocity with black and death metal extremity into compact, caustic bursts of noise. Operating out of the city's underground, they favor speed and ferocity over nuance — short, punishing songs with no room for comfort.

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. Their work is less interested in brutality for its own sake than in using death metal's toolkit to explore unfamiliar sonic territory.

Moon Witch is a Dayton, Ohio band formed in 2021 that tears through black metal, death metal, and grindcore in roughly equal measure, trading in speed and ugliness with clear enthusiasm. Their Bandcamp handle — moonwitchusbm — signals a commitment to underground black metal aesthetics even as the grind influence pulls them toward pure noise.

Moonchapel is a brand-new black-death metal project from Westminster, Maryland, formed in 2025. Still in its earliest stages, the band draws on the intertwined traditions of black and death metal — blastbeats, tremolo riffs, and an atmosphere pitched somewhere between the infernal and the void.
