Los Angeles psychedelic sludge merchants Garbeast layer sun-scorched fuzz over cavernous doom tempos, conjuring something hallucinatory and heavy in equal measure. Since forming in 2021 they've leaned hard into the ritualistic, slow-burning end of the LA underground.

Lake County, Illinois quartet Garden of Darkness blends gothic gloom, power metal ambition, and progressive architecture into a dramatic and ornate style that emerged in 2020. Equal parts darkness and grandeur, they occupy an unusually wide corner of heavy music.

One of the more enduring acts in the American melodic death metal underground, Gaithersburg, Maryland's Garden of Shadows has been weaving atmospheric grandeur into aggressive death metal since the early 2000s. Their sound leans cinematic without ever losing its teeth.

Louisville, Kentucky's Gardens of Grey is a freshly formed project threading together doom, death, and post-metal into something mournful and expansive. Active since 2024, they reflect Louisville's long tradition of heavy, emotionally dense underground music.

Hailing from Normal, Illinois, Garg deals in raw, no-frills black metal that embraces the underground's most primitive and unpolished instincts. Formed in 2022, they work in the stripped-back style that prioritizes atmosphere through harshness over any kind of technical refinement.

Connecticut's Gargamel marries symphonic grandeur to black metal extremity, building elaborate, orchestral arrangements atop a still-venomous core. The project has been active since 2010, amassing a catalog that tilts theatrical without abandoning its harder impulses.

Springfield, Illinois outfit Gargantuan merges the atmosphere of black metal with the pummeling density of death metal into a sound that's as expansive as its name implies. Since 2019 they've built a reputation in the Illinois underground for uncompromising extremity.

Santa Cruz, California's Gargantula has been spinning its web since 2015, weaving together progressive, stoner, doom, and death metal into something strange and sprawling. Their compositions wander freely across tempos and moods, held together by a psychedelic, spidery sensibility.

Gargoyl formed in 2018 as a collaboration between Revocation guitarist Dave Davidson and guitarist/vocalist Luke Roberts, who met while on tour and discovered a shared musical sensibility rooted in progressive metal, 1990s grunge, and avant-garde rock. The project's self-titled debut (2020), released via Season of Mist, blends dark, dissonant progressive metal structures with Alice in Chains-influenced vocal harmonies and a brooding alternative rock atmosphere that diverges significantly from Davidson's main band. Rounded out by bassist Brett Leier and drummer James Knoerl, the band demonstrated that Davidson's compositional range extends well beyond death metal's conventional parameters.
