San Francisco's The Undying fuse symphonic orchestration with technical death metal brutality and deathcore breakdowns, a combination that has driven their sound since forming in 2011. Their music is uncompromising in its ambition, stacking complexity and cinematic scale into the same passages.

Torch Jaw come from Tehachapi, California — a small desert town in the mountains south of the San Joaquin Valley — and forge a hybrid sound that draws from groove metal's rhythmic authority, deathcore's sonic brutality, and traditional heavy metal's riff-centric sensibility. Formed in 2021, they represent the kind of geographically isolated band that pushes genre boundaries out of creative necessity.

Riverside, California's Torn Within, formed in 2022, plays deathcore with a death metal core, bringing the genre's characteristic low-tuned heaviness and rhythmic punishment to the Inland Empire's underground scene. The greater Los Angeles region's long deathcore infrastructure provides a strong platform for their brutality.
