The Mountain King

Persistence in Mourning is the Oklahoma City-based solo funeral doom project of Andy Lippoldt, active since 2006, described as sitting between funeral doom, death industrial, power electronics and death metal.

Solo instrumental drone/doom/dark-ambient project by Tim Roberts (Savannah, GA). The substantial release The Prophet Killed (2013) is a concept album about a Biblical prophet, built from eight very long-form tracks (1:37 to 16:47, ~70 min) of sustained tones, slow doom-weight passages and dark-ambient atmosphere per the artist's own genre tagging (Ambient, Dark Ambient, Doom, Drone Metal, Experimental).

Beneath the Sod is the solo funeral/industrial doom project of Irish musician Ray Keenaghan (Wreck of the Hesperus), formed 2017. Releases include Circling the Drain (2017, Fort Evil Fruit), the split cassette Transmorphic Eye (2018, with Crypticum), and a self-titled 2021 EP on Cursed Monk Records described as harsh, synth-laced industrial doom metal with guest vocals from Richard Carson.

Ghostmass (大鬼眾) is a Beijing improvisation collective formed in 2021 from a shared passion for drone, doom, and extreme metal, filtered through harsh noise and free improvisation. Reviewer Michael Scharf (Outside Noise) describes their 2024 album 'Ghost Meditation' as evolving from chaotic noise toward a more structured, doom-metal-inspired sound, with anguished throat-singing-style vocals over grating feedback and power electronics. The lineup draws members from Beijing noise-rock scene acts Carsick Cars and Soviet Pop.

Opium Warlords is the solo-turned-trio outlet of Sami Albert Hynninen (Albert Witchfinder of Reverend Bizarre), stretching doom metal into extended drone-riff meditations with minimal percussion. Since 2010 he has been joined by drummer Erkki Virta and keyboardist Laura Länsimäki, though the project remains built around Hynninen's distorted bass and bleak conceptual framing. Six albums deep on Svart Records, the band trades hooks for duration, dissolving riffs into noise and silence.

Black Mayonnaise is the long-running one-man bedroom project of Mike Duncan from Akron, Ohio, active since August 1991. It blends heavily detuned, distorted doom/sludge guitar with drum-machine programming, tape loops and cut-up sonic manipulation into a lo-fi, ambient/psych-drone-inflected sound. Cited influences include old Godflesh, old Carcass, Butthole Surfers and Big Black; notable releases include TTSSATTSR (2004) and the retrospective compilation When You Get Caught Between the Moon and Boston Harbor (2011). (Verified spelling: the RYM scout note had a typo, 'Black Mayonaise' — the real band spells it 'Black Mayonnaise'.)

Zatvor is a long-running experimental doom/sludge/drone project from Kursk, Russia, active since 1996. Their 2018 release 'Ключ земли' is a single 49-minute piece blending guitars, drums, flute, and saxophone with noise and electronic textures over a drone/doom foundation, mixed and mastered by James Plotkin.

Thrones is the long-running solo project of American bassist Joe Preston, begun in 1994 and given to bass-heavy doom, avant-garde noise rock and experimental drone. Preston is a scene hub in his own right — a former member of Earth and the Melvins and a guest on Sunn O)))'s recordings — and Thrones channels that low-end lineage into one-man records like the Southern Lord compilation Day Late, Dollar Short (2005). The music pairs crushing riffs and heavily processed vocals with an eclectic, unpredictable sensibility.

All Are to Return is a mostly-anonymous two-person industrial doom/noise project (credited only as 'F' and 'N') based in the Netherlands, releasing since 2020 via Tartarus Records. Their records (II, 2021; III, 2024; Limen, 2025) build colossal, FX-drenched noise-scapes from pulsing synths, doom-paced percussion, and screamed vocals, with lyrical/conceptual focus on ecological collapse and climate catastrophe. No gamelan or other Indonesian/Balinese percussion instrumentation was found in any source consulted, despite that being the scouting lead's premise — the confirmed sound is industrial/doom/noise, not gamelan-folk fusion.

Ufomammut are an Italian power trio formed in 1999 in Tortona, dealing in a signature strain of psychedelic sludge that spans doom, stoner, sludge and drone metal. Their music favors lengthy songs built on repeated heavy riffs, droning vocals and a heavy use of synths and sound effects, staged live with synchronized psychedelic visuals by founders Poia and Urlo's Malleus art collective. Their most recent studio albums — including Fenice (2022) and Hidden (2024) — appear on Neurosis's Neurot Recordings.
