New York guitarist Sebastian Marino launched this project in 2020 as a vehicle for hard-hitting heavy metal and hard rock that foregrounds technical guitar work without losing sight of melody or feel. The solo project format gives Marino the freedom to pursue a tightly constructed sound that draws from classic metal lineage while shaping it through a contemporary lens. It's a showcase for a player who knows exactly what he wants from the genre.

Los Angeles's Sebek — named for the ancient Egyptian crocodile deity — forge a blackened thrash attack that's as feral and aggressive as their namesake. Active since 2015, the band channels the raw, speed-obsessed chaos of early black/thrash into something that feels genuinely dangerous rather than merely nostalgic. Their LA origins ground them in a city with deep extreme metal roots, and they honor that lineage without sounding derivative.

Second Shooter arrived in Los Angeles in 2023 bringing a groove metal approach that prioritizes rhythmic punch and low-end brutality over melodic concession. As a newer entry into the LA metal scene, they've established themselves quickly with a direct, no-frills heaviness built around the kind of locked-in riff patterns that make groove metal compelling at its core. The name suggests a band comfortable playing the supporting role — until they're the main event.

Des Moines's Second Side have been navigating the space between thrash aggression, groove-metal momentum, and alternative metal experimentation since 2015. The Iowa trio's approach resists easy categorization — the thrash instincts keep things sharp and forward-moving, while the alternative influences introduce texture and dynamics that prevent the sound from calcifying into formula. They're a product of the Midwest DIY underground where versatility is a survival trait.

New York death metal outfit Secrecy have been carving out their corner of the underground since 2014, delivering the kind of dense, uncompromising brutality the state's metal scene has long been known for. Their approach favors heaviness over accessibility, rooting itself in the cavernous traditions of American death metal without apology.

Hailing from Chelmsford, Massachusetts, this incarnation of Secrecy takes the thrash blueprint and runs it through a New England sensibility — tight riffing, aggressive tempos, and a no-frills attitude that nods to the genre's Bay Area and East Coast forebears. Active since 2014, they represent the kind of working-class thrash that keeps the underground honest.

Los Angeles avant-garde death metal project Secrelict emerged in 2023 with a mandate to push the genre past its conventional borders, blending dissonance, unconventional structures, and experimental textures into a distinctly modern form of extremity. The band's approach treats death metal as a starting point rather than a destination, fracturing familiar heaviness into something genuinely unsettling.

Los Angeles heavy metal act Secular Stranger draw from the classic tradition without surrendering to nostalgia — their music has the weight and craft of the genre's foundational era filtered through a contemporary perspective. Since forming in 2014, they've pursued a style that prioritizes strong songwriting and muscular riffs over either retro cosplay or modern reinvention.

Fresh out of Huntington Beach, California, Secularis arrived in 2025 as one of the newest entries in the American black/death underground, combining the icy hostility of black metal with the visceral attack of death metal. Even at this early stage, the project signals a willingness to operate in the extremes where both genres converge most violently.
