Lowell, Massachusetts's Cunt Cuntly started as a bedroom solo project before expanding into a full band that pressed progressive ambition into a deathcore and death metal framework. Active from 2011 to 2017, they built an eclectic discography that showed a restless willingness to cover everything from Judas Priest to Creedence Clearwater Revival alongside their original extremity.

Los Angeles's Cuntamination operate in the most punishing end of brutal death metal, favoring maximum heaviness and genre-specific extremity over nuance or experimentation. The Southern California act is part of a region that has quietly sustained a fertile underground brutal death scene operating well below the mainstream radar.

North Carolina's Cuntplague are an anti-religion black metal band who have waged an auditory battle against modern hypocrisy since forming in 2012, with releases on Flamecult Records that traffic in raw, confrontational extremity. Their 2013 self-titled debut established a sound rooted in old-school black metal nihilism and contempt for organized faith.

Cedar Rapids, Iowa's Cur channel groove metal's heavy mid-paced momentum into a blunt, meat-and-potatoes heavy metal framework, favoring direct, riff-driven aggression over technical complexity. The Iowa band represent the Midwest's deep tradition of blue-collar, no-frills metal made for the road and the pit.

Troy, New York's Cur inhabit the colder reaches of atmospheric black metal, blending the Upstate New York landscape's industrial bleakness with expansive, textured guitar work and a raw, introspective approach to the genre. The Capital Region's extreme underground has long operated in the shadow of New York City, but projects like Cur make it clear that the real darkness runs north.

Sacramento's Cura Cochino — Spanish for 'dirty priest' — are a husband-and-wife doom act whose morbid, Black Sabbath-rooted sound is transported into Baja California when vocalist Priscila sings in Spanish and unleashes grito Mexicano howls over grinding, funeral-weight riffs. Their doom en español is something singular in the American metal landscape.

Indianapolis's Curb work the volatile intersection of black metal's atmospheric menace and death metal's structural brutality, a combination that has always felt at home in the Midwest's underground extreme scene. The Indiana act operates independently, adding to a regional lineage that includes Coffinworm and Demiricous.

Chicago's Curbstomp combined the amphetamine pace of thrash with the swampy heaviness of sludge metal into a direct, combative sound that fit naturally into the Windy City's abrasive underground. Active from 2000, the band operated as an independent act before eventually parting ways.

Chicago's Curdled push death metal toward its most putrid and decomposing extremes, delivering the kind of ugly, uncompromising underground death that the city's metal scene has sustained for decades beneath the gaze of more prominent acts. The band operates in the tradition of Chicago's deep-rooted death underground.
