Out of Antioch, California since 2015, Demonsmoke drag sludge and doom metal through the Bay Area's grimy underbelly, building suffocating walls of distortion laced with a toxic, crawling menace.

Los Angeles-based Dowager has been building doom and sludge monoliths since 2014, a fitting project for a city where everything from the traffic to the smog seems to move at a funeral pace. Their sound carries the sprawling, oppressive weight of L.A.'s vastness — slow tempos, massive guitar tones, and a sludge-influenced abrasion that keeps the prettiness of doom metal from becoming comfortable. There's a distinctly urban ugliness to their sound, music made in and for a city that grinds people down.
