Los Angeles's Faetooth occupies the intersection of doom, sludge, and post-metal — a trio of subgenres that reward patience and reward volume — building their layered, emotionally heavy sound since forming in 2019.

Los Angeles' Failure were criminally overlooked during the '90s alternative rock explosion, crafting densely layered space-rock that split the difference between My Bloody Valentine's shoegaze and Tool's progressive metal. Albums 'Comfort' and 'Fantastic Planet' are now recognized as ahead-of-their-time masterpieces, with the latter's 'Stuck on You' becoming a belated hit. Their 2014 reunion after an 18-year hiatus was greeted with the reverence they deserved from the start.

San Bernardino, California's Fait has been playing traditional heavy metal since 2014, carrying the torch in the Inland Empire — a gritty stretch of Southern California that has its own claim on metal's working-class roots.

San Francisco's Faith No More need little introduction: since their mid-1980s beginnings they redefined what metal and rock could be, and their 2015 reunion confirmed that their restless, genre-dissolving approach to avant-garde alternative metal still has nowhere obvious to land.

One of Los Angeles' longer-running death metal acts, Fallen Angel have persisted since 1992 in a city that's churned through thousands of bands — a testament to their commitment to the form. Their longevity in the L.A. underground speaks to a stubborn dedication to death metal's roots.

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.

Santa Rosa, California's Fallen Prey are fresh to the scene, forming in 2025 with a straightforward thrash agenda in a Northern California county with deep roots in aggressive music. They're early in their run, but the Sonoma County metal tradition gives them plenty of precedent to draw from.

Los Angeles black/death act Fallen Soul have been operating in the city's sprawling underground since 2017, where the sheer size of the scene lets extreme metal acts pursue uncompromising sounds without chasing commercial viability. Their dual-genre identity brings both frost and brutality to a city not typically associated with either.

Los Angeles stoner metal act Fallen Suns have been letting their riffs breathe since 2016, drawing on Southern California's long tradition of fuzz-soaked heavy rock and desert-influenced slowburn. Their music moves at the pace of heat — unhurried, thick, and designed to expand in open space.
