San Jose's Skinner, formed in 2022, blend the melodic ambition of power metal with the velocity of thrash — a Bay Area project that draws on the region's rich legacy of high-energy, technically inclined heavy metal.

Corona, California's Skinslip work the intersection of sludge and doom, conjuring slow, weight-bearing riffs that reflect the smoggy, sun-bleached desolation of the Inland Empire since their formation in 2014.

Pomona, California's Skitz bring a heavy metal and hard rock sensibility to the Inland Empire underground, a scene formed since 2011 that blends the blue-collar grit of the 626 with classic heavy riffing.

A separate Santa Rosa, California outfit also formed in 1985, this Skitzo drew from the thrash explosion happening across the Bay Area at the time — capturing the speed and aggression that defined the mid-decade California underground.

California's Bay Area folk and Viking metal outfit Skogshallen have been active since 2011, layering Norse-inspired themes and folk instrumentation over heavy metal foundations in a region more associated with thrash — making them a genuinely distinct voice in the Northern California scene.

Los Angeles's Skorched pull from thrash, death metal, and hardcore in equal measure — a crossover-minded trio active since 2017 that reflects the city's long tradition of genre-blurring underground acts where pit culture and riff weight converge.

Sacramento's Skribble began in 2000 at the height of nu-metal's commercial peak, blending those chunky, down-tuned grooves with death metal's aggression — a trajectory that saw the band shed the radio-friendly angles in favor of darker, heavier material over the years.

Fresno's Skull Incision have been active since 2010, working in the ugly overlap between death metal, grindcore, and sludge — a combination that makes for short, punishing tracks coated in downtuned filth and California Central Valley grime.

A California heavy/thrash metal outfit that materialized in 2025, Skullbuggery appears to be taking cues from classic metal's swaggering riff vocabulary, planting a tongue-in-cheek name on a foundation of heavy, speed-driven material.
