Auburn, California's Those Who Live in Death formed in 2025, making them one of the newest entries in the American black metal underground.

Sebastopol, California's Thought Vomit have been dealing in Bay Area-influenced thrash metal since 2016, channeling the Northern California tradition of speed, riff density, and unhinged energy that defined the genre's American peak. Their name announces the aesthetic: raw, unfiltered, and relentlessly aggressive.

San Diego's Thousand Below craft emotionally heavy post-hardcore that spans from crushing metalcore anthems to atmospheric rock and heartfelt ballads, anchored by vocalist James Deberg's ability to channel raw vulnerability into cathartic musical moments. Formed in 2016 after Deberg's departure from Outlands, the band quickly earned a deal with Rise Records and built a devoted following with albums that wear their heart on their sleeve. Their fourth studio album 'Buried In Jade' demonstrates the continued evolution of a band that refuses to be confined to a single sonic identity.
