Auburn, Washington groove/thrash metal band Cicatrix lock into heavy mid-tempo grooves underpinned by tightly coiled thrash riffing and punchy production. Their approach favors rhythmic impact and head-down momentum.

Raleigh, North Carolina sludge metal act Cigarettesmokingman drag their songs through thick, tar-slow tempos and corrosive guitar tones that owe as much to southern atmosphere as to extreme metal. Their music feels as worn and relentless as the name suggests.

New Orleans doom/stoner/sludge band Cikada channel the murky, humid atmosphere of their city into sprawling, fuzz-drenched compositions that sit at the intersection of southern sludge and psychedelic doom. Their sound draws naturally from the well of Eyehategod and Crowbar.

Rock Springs, Wyoming black metal project Cimejes conjure bleak, isolated darkness that fits the desolate high plains landscape of their home state. Their recordings favor raw production and grim atmosphere over accessibility.

Lancaster, Pennsylvania folk/heavy metal band Cimmerian draw on ancient mythology and pagan tradition to craft melodic, epic metal with a raw folk undercurrent. Their sound evokes the savage world of the Hyborian Age that inspired their name.

New Lenox, Illinois death/progressive metal act Cimmerian build technically demanding compositions that push death metal heaviness through intricate progressive structures. Their writing is dense and ambitious, rewarding repeated listens.

New London, Connecticut doom/stoner duo Cinder Mage craft slow, hypnotic riff worship drenched in fuzz and reverb, conjuring occult imagery through heavy, ritualistic song structures. Their music moves like lava — deliberate, unstoppable, and scorching.

Cinderella's Tom Keifer names the solo and touring identity of the singer, guitarist, and songwriter best known for fronting the Philadelphia-area hard rock band Cinderella. Keifer's musical history starts with the bluesy, raspy-voiced side of 1980s heavy rock: Night Songs gave Cinderella a glam-metal breakthrough, but Long Cold Winter and Heartbreak Station revealed deeper roots in slide guitar, Stonesy swagger, country-blues phrasing, and arena-sized ballads. His solo work with #keiferband, beginning with The Way Life Goes and continuing through Rise, keeps that foundation while sounding less tied to the original glam era. The songs lean on weathered vocals, hard-rock guitars, piano accents, gospel-tinged backing voices, and a storytelling approach shaped by survival, vocal injury, and reinvention. Live, the project connects Cinderella staples with newer material, so the line between legacy act and current band is deliberately porous. Keifer's value to hard rock is not only nostalgia; it is the way his voice and writing keep blues grit inside loud, hook-driven songs without making either side feel ornamental for contemporary hard-rock audiences.

Philadelphia progressive/heavy metal band Cipher combine classic heavy metal songwriting with adventurous, prog-influenced arrangements and sophisticated harmonic choices. Their music rewards close listening while never sacrificing heaviness for complexity.
