Purple AQP is a heavy metal and hard rock solo project by Victor Calvo Llerena, based in Arequipa, Peru. Drawing inspiration from classic heavy metal and hard rock of the 1970s and 1980s, the project released its debut demo Empire Arise in 2019, followed by the full-length Rise and Fall of the Inca's Empire in 2022. The name combines a nod to Deep Purple with AQP, the airport code and common abbreviation for Arequipa.

Scranton doom and stoner metal band born in 2022, stacking fuzzed-out riffs and tar-slow tempos in the tradition of the Northeast's working-class heaviness. Their name alone signals a commitment to lung-collapsing low end.

New Jersey progressive death metal and metalcore hybrid formed in 2023, fusing the technical ambition of modern death metal with the structural hooks of metalcore in a combination that reflects the dense, polyglot heavy music scene of the mid-Atlantic.

La Porte, Indiana melodic power metal band active since 2014, trafficking in soaring vocals, double-bass gallop, and anthemic chord progressions drawn from the European power metal tradition — an unusual outpost for the style in the American Midwest.

Kingsport, Tennessee death metal act formed in 2024, representing the newer generation of Appalachian-region extreme metal with a straight-ahead, no-frills approach to the genre's foundational brutality.

Bay Area extreme metal mainstay since 2005, blending death metal, crossover thrash, and grindcore into a chaotic, low-fidelity assault that draws on the Northern California underground's long tradition of genre-defying extremity.

Houston thrash metal band formed in 2005, operating in the city's historically fertile extreme metal underground with the straightforward speed and aggression that defines the Texas approach to the genre.

Meriden, Connecticut thrash metal band from 2005, part of the scrappy New England underground metal scene that has quietly produced some of the region's most uncompromising aggressive acts.

Puscifer is Maynard James Keenan's Arizona-rooted art-rock project, developed as a deliberately flexible outlet apart from Tool and A Perfect Circle. Rather than functioning like a conventional rock band, Puscifer works as a rotating creative laboratory centered on Keenan, Mat Mitchell, Carina Round, and a changing network of collaborators. V Is for Vagina introduced a sly, electronic, desert-dust version of industrial-tinged rock, while Conditions of My Parole, Money Shot, Existential Reckoning, and later releases refined the balance between groove, atmosphere, satire, and emotional unease. The music often moves at a controlled simmer: bass lines pulse, electronics flicker, guitars appear as texture or threat, and the vocals trade between Keenan's dry menace and Round's melodic gravity. Puscifer belongs in a heavy-adjacent directory because its darkness, industrial influence, and alternative-rock weight sit near metal culture even when the arrangements avoid traditional riff dominance. The project's history is also inseparable from performance art, video, and character work, but the songs endure because beneath the absurd framing sits patient, moody, carefully engineered rock architecture.
