Author & Punisher is the solo industrial doom and drone metal project of San Diego-based mechanical engineer Tristan Shone, active since 2004. Shone performs entirely on custom-fabricated machines and controllers called Drone Machines, devices that grew out of his masters thesis at the University of California, San Diego, and which draw directly from industrial robotics and automation. His catalog includes numerous releases on Relapse Records, with Nocturnal Birding arriving in October 2025 and marking the first time a second full bandmember, guitarist Doug Sabolick, has joined the project.

California's Chatterbox fused industrial metal's mechanized texture with thrash's serrated riffing, staking out a harsher corner of the early-90s industrial metal scene that was building momentum alongside acts like Ministry and Skinny Puppy. Their sound carries the abrasive, mechanical quality of a region generating some of the period's most experimental heavy music.

Moraga, California's Children of the Phantom occupies a strange space between oppressive doom metal and the cold, mechanical textures of industrial metal. The collision produces a dense, atmospheric sound that feels as cinematic as it is heavy.

Los Angeles-based Dawn of Ashes have spent over a decade fusing industrial electronics with melodic black metal, crafting a sound as cold and synthetic as it is primal. Their EBM roots push the project into genuinely unnerving territory where machines and darkness share equal billing.

Pleasanton's Death Machine fuse industrial grit with progressive ambition, constructing mechanized soundscapes that grind and evolve in equal measure. Since 2016, they've been building a cold, calculated sonic architecture.

Los Angeles's Deliverance carry a storied legacy reactivated in 2020, blending speed metal and thrash with industrial elements in the tradition of the band's long history. Operating out of the LA metal scene, the band weaves mechanical menace through the kinetic force of high-octane thrash, a combination that has made them fixtures of the underground for decades across multiple incarnations.

San Francisco's Depressor have been mutating metal since 1995, beginning their career with abrasive industrial metal before pushing further into brutal death metal territory. This long-running Bay Area act represents a rare evolution from mechanized noise and grinding machinery into something even more viscerally crushing.

San Francisco's Errorgeist fuses industrial metal's mechanical precision and metallic texture with death metal's ferocity, treating programmed and processed sounds as weapons alongside more conventional brutality. Formed in 2015, the band approaches the intersection of machine and flesh as inherently hostile territory.

Sacramento's Fallen Man fuse industrial, thrash, and death metal into something mechanical and ferocious, active since 2015 in a Northern California city that's produced some of metal's most uncompromising acts. The industrial thread runs cold through their sound, adding processed menace to the traditional metallic assault.
