Emerging from Florida in 2020, Worm began as a raw black/death/doom entity before evolving into something considerably more elaborate — later recordings layer symphonic arrangements over the suffocating weight of doom and the corrosive grain of black and death metal. The band's trajectory from crude burial-ground aesthetics toward orchestrated darkness is one of the more striking transformations in recent underground extreme metal.

York, Pennsylvania's Worm March has been building a catalogue of death/doom metal since 2019, channeling the mid-Atlantic's capacity for grey, grinding heaviness. Their approach leans into the suffocating intersection of slow death metal riffing and true doom pacing, creating a dense and oppressive atmosphere.

Boston's Wormwood — not to be confused with their Illinois namesake — emerged in 2015 with a sound rooted in sludge and doom metal, drawing on the Northeast's long tradition of heavy, miserable riffing. Their music carries the grim weight that characterizes the best of the city's underground heavy scene.

Seattle's Worn Away have been an interesting shape-shifter since their 2013 formation, moving from doom and stoner metal origins toward a harder-edged crossover thrash and death metal sound over time. That evolution mirrors a broader restlessness in the Pacific Northwest underground, where genre boundaries are treated more as starting points than destinations.

Atlanta's Wounds of Recollection emerged in 2014 from the intersection of funeral doom and black metal, building monolithic walls of grief before expanding into post-black metal and post-rock territory. The band's evolution traces an arc from suffocating heaviness toward something more expansive and bittersweet, without ever fully letting go of its funeral roots.

San Francisco's Wrack have been hauling sludge and doom through the Bay Area underground since 2016, blending the city's storied tradition of heavy music with slow, corrosive riffs built for endurance rather than speed. Their sound evokes the weight of the fog-laden coastline — dense, unhurried, and unrelenting.

Silver Spring, Maryland doom metal outfit formed in 2018, drawing from the slow-moving, grief-laden tradition of the genre from the Washington D.C. suburb. Their sound favors crushing weight over speed, embracing the long-form misery that doom demands.

Columbus, Ohio outfit Wurm Sun fuse the crawling weight of doom metal with the abrasive filth of sludge, conjuring a suffocating heaviness that feels born from the industrial grimness of the Midwest. Active since 2022, their sound prioritizes atmosphere and oppressive volume over speed.

Tennessee's Wëëdkiller are a nascent stoner/doom act formed in 2026, crafting slow, hazy heaviness from the fertile Southern underground where heat and humidity seem to seep into every downtuned riff. Their name and sound together point toward a band comfortable wallowing in the slow burn.
