Los Angeles heavy metal outfit Cloak Creature bring a lurking, shadowy energy to the LA metal scene, drawing on classic heavy metal tradition filtered through the city's expansive underground. Their music is riff-driven and deliberate, favoring menace over flash.

Vancouver, WA's Cloak of Displacement inhabit the slow, suffocating intersection of black metal and drone, constructing vast, formless pieces built on dissonance and sustained tension. Their work is meditative and unsettling in equal measure.

Nashville's Cloaked produce raw, primitive black metal with a deep commitment to the genre's most unadorned and hostile traditions. Their recordings are deliberately lo-fi and confrontational, rejecting any polish in favor of pure darkness.

Cloakroom formed in Indiana in June 2012, developing a sound that drew equally from shoegaze's textured reverb, 1990s slowcore melancholy, and hardcore's physical weight, with reference points including Hum and Red House Painters. Their debut Further Out appeared in 2015, and the band went on to release Time Well (2017) and Dissolution Wave (2022) on Relapse Records. Their 2025 album Last Leg of the Human Table continued their exploration of heavy, introspective guitar music.

Aurora, IL death/thrash act Clocktower bring a hard-hitting, no-nonsense approach to classic extreme metal, rooted in the long tradition of Chicago-area underground metal. Their music is tight, aggressive, and built around the kind of riff-forward songwriting that defined American thrash and death in their early years.

A one-man black metal project from Roslyn, New York, Clocktower of Hiraeth was conceived by the entity known as Myghûl the Drowned in 2018. Built around themes of history, addiction, and anti-religion, the project carved out a bleak atmospheric sound before going quiet.

A progressive metal outfit from the Philadelphia suburb of Broomall, Pennsylvania, Clockwork blended symphonic prog complexity with technical metal muscle, drawing comparisons to Yes and Dream Theater. Their lone album Surface Tension showcased lush keyboards, intricate rhythms, and soaring guitar melodies.

Fort Lauderdale heavy metal veterans Clockwork Revolution bring a seasoned pedigree to their sound, drawing on former members of Yngwie Malmsteen, Crimson Glory, and Kamelot. Fronted by Wade Black, the band delivers polished classic-leaning metal that reflects decades of experience in the genre's upper tiers.

A Nashville psychedelic doom outfit formed in 2009 by Belmont University students, Clorange channeled Black Sabbath, Sleep, and Electric Wizard into a hazy, riff-heavy sound. They released the album Instinct in 2012 before disbanding the same year.
