Rochester, New York's Killed with Cash have been shredding crossover thrash since 2014, carrying on the genre's blue-collar irreverence with riffs that hit as hard as the humor. Part Leeway, part Municipal Waste, fully upstate New York.

Staten Island's Killen play traditional heavy metal with the no-nonsense working-class energy of the outer boroughs, formed in 2016 and drawing on the timeless vocabulary of riff-driven power and melodic hooks.

New York's Killerwatts charge through thrash and heavy metal with an electrified aggression that suits the name, formed in 2012 and built around the genre's fundamental pleasures: velocity, volume, and riffs that don't let up.

Kim Gordon is an American musician, vocalist, bassist, guitarist, writer, and artist whose work with Sonic Youth helped define noise rock and American underground alternative music. Born in Rochester and raised partly in California, she entered New York's early-1980s art and no wave world before co-founding Sonic Youth in 1981 with Thurston Moore and Lee Ranaldo. Gordon's presence in that band was central: her bass lines, guitar textures, deadpan vocals, and conceptual instincts gave the music a cool but unstable charge. Sonic Youth turned dissonance, alternate tunings, feedback, and punk method into a language that influenced grunge, riot grrrl, indie rock, and experimental guitar music. Gordon's solo work and projects such as Free Kitten and Body/Head continued that interest in abrasion, space, and performance, later adding trap-influenced production, spoken delivery, and harsh electronic edges. She fits accepted scope through noise rock, post-punk-adjacent art rock, and experimental heavy guitar music. Gordon's importance is not only historical. Her music keeps asking how rock can sound strange, physical, and critical without becoming academic. At her strongest, she turns minimal gestures, damaged textures, and a skeptical voice into something confrontational and magnetic.

Tarrytown, New York progressive metal band Klepsydra formed in 2016 with an ear for labyrinthine song structures and expansive dynamics. Sitting in the shadow of New York City, their work reflects the ambitious, searching quality of the region's prog-minded metal underground.

Koyo are a Long Island band whose music connects melodic hardcore, pop punk, and emo to the region's deep hardcore lineage. Formed by musicians who grew up around the Long Island hardcore scene, the band carries clear links to groups such as Silent Majority, The Movielife, Taking Back Sunday, and the broader LIHC tradition while still writing songs that feel current. Their sound is fast, melodic, and emotionally direct: guitars ring and surge, drums push with hardcore urgency, and Joey Chiaramonte's vocals land between pop-punk melody and scene-rooted conviction. Koyo fit accepted scope through melodic hardcore, hardcore-adjacent punk, and pop punk. They are a useful example of how modern bands can come from hardcore culture without sounding like pure beatdown or revivalist youth crew. Releases such as Painting Words Into Lines, Drives Out East, Would You Miss It?, and later material show a band invested in memory, friendship, grief, place, and the strange emotional geography of growing up in a scene. Koyo's best songs work because they feel communal without becoming vague. The band writes hooks, but the live energy and hardcore foundation keep the music grounded, physical, and unmistakably tied to Long Island.

Long Island's Kraegeloth has been honing melodic death metal since 2017, bringing Scandinavian-influenced craft to New York's dense and competitive extreme metal underground. Their emphasis on melody and atmosphere distinguishes them from the region's more brutality-focused acts.

New York experimental death metal project Kryvydya has been bending the genre's conventions since forming in 2022. Their music treats death metal's structural brutality as a jumping-off point for dissonance, abstraction, and experimentation that resists easy categorization.
