Minneapolis death metal band Coagulate delivered Finnish-influenced brutality across releases including the 2020 album The Art of Cryptosis, drawing praise from Decibel for their bone-snapping riffs and cavernous low growls. Inspired by Convulse's sickness, they built a lean and punishing sound before disbanding.

A death metal band from Parlin, New Jersey originally active from 1998 to 2004 with a brief reunion in 2010-2012, Coagulated Blood left behind a small catalog of limited physical releases that have since been made available digitally. Members went on to form melodic black metal act Dark Sacrament.

A St. Louis death metal and grindcore act, Coagulating operate deep within the underground, where blunt brutality and noise collide. Their existence is largely undocumented beyond their regional scene presence.

Coal Chamber were among the first wave of nu-metal bands to emerge from Los Angeles in the mid-'90s, pairing Dez Fafara's sneering vocals with dark, gothic-tinged riffs and industrial textures. Their 1997 self-titled debut and follow-up 'Chamber Music' helped establish the nu-metal blueprint alongside peers like Korn and Deftones. Though Fafara went on to greater commercial success with DevilDriver, Coal Chamber's grimy, theatrical take on heavy music remains a touchstone of the era.

Coalesce formed in Kansas City, Missouri in 1994, pioneering an abrasive and technically demanding strain of metalcore characterized by odd time signatures, dissonant guitar interplay, abrupt dynamic shifts, and aggressive vocals. The band released key records including Give Them Rope (1997) and 0:12 Revolution in Just Listening (1999) on Hydra Head Records, establishing them as foundational figures in both metalcore and mathcore. They broke up in 2010 and have since performed reunion shows.

Minneapolis death-doom outfit Cobra Czar pair crushing low-end heaviness with groove-driven swagger and mid-paced menace. They occupy a filthy intersection of groove metal and death metal that hits hard in the Twin Cities underground.

Portland, Oregon stoner metal band Cobra Thief deal in hazy riffs, pounding rhythms, and the kind of heavy psych grooves that flourish in the Pacific Northwest underground. Their music carries the loose, fuzzed-out energy that defines the stoner metal circuit.
