Olympia, Washington's Moldy Castle have been playing traditional heavy metal since 2011 with the kind of unpretentious dedication that the city's underground scene tends to reward. They favor the classic forms of the genre without chasing trends, keeping their sound rooted in the essentials.

Miami's Molech channel the ferocity of Florida death metal through a thrash-driven attack, combining the state's legacy of brutal extremity with the speed and aggression that thrash demands. Formed in 2021, they bring fresh energy to a city with deep roots in extreme metal.

New York's Molested Nun, formed in 2023, work in the brutal death/goregrind space where provocation and extremity are inseparable from the aesthetic — anti-religious imagery and punishing sonics go hand in hand. Despite being a young act, they slot directly into New York's long history of no-apologies extreme metal.

McLean, Virginia's Molgah have been playing straightforward death metal since 2020, emerging from a suburb of Washington D.C. that might seem unlikely but quietly contributes to the DMV's surprisingly active underground. Their approach is unadorned and direct.

Boston's Mollusk combine the crushing weight of sludge with the suffocating drag of doom metal, creating music that feels appropriately deep-sea and oppressive. Formed in 2020, they've found their place in Boston's storied heavy music underground with a sound that's slow, heavy, and deliberate.

Los Angeles' Molocchio, formed in 2024, take their name from the Italian evil eye and bring a similarly malevolent edge to their raw black metal, emerging from the L.A. underground with an aesthetic rooted in curse and occult dread. A genuinely new entry in the city's active black metal scene.

This US-based Moloch, active since 2007, traffics in raw, uncompromising black metal with the kind of underground anonymity — no state or city listed — that fits the genre's anti-spectacle philosophy. Their long tenure and sparse public presence suggest a project driven purely by the music itself.

Tulsa, Oklahoma's Moloch have been delivering black metal from the southern plains since 2007, occupying a regional niche that carries the genre's misanthropic ethos into an unexpected geographic context. Tulsa's isolation from major metal scenes seems to fuel rather than hinder their commitment to the form.

Formed in 2025 in Birmingham, Alabama — a city with deep roots in heavy music — Molten Valley deal in the slow and suffocating intersection of doom and sludge metal, dragging riffs through tar-thick tempos and oppressive atmosphere.
