Overmars

The dark-ambient/doom project of Matron Thorn (also of Ævangelist and Præternatura), based in Tampere, Finland, with six full-lengths 2021-2024. Bandcamp self-tags consistently describe it as experimental dark-ambient doom metal with post-rock and soundtrack qualities and occult lyrical themes — a slower, more spatial sibling to Thorn's more extreme-metal-facing projects.

Khlyst is an American experimental drone/doom project formed in New York in 2006, built around guitarist James Plotkin (Khanate, OLD, Phantomsmasher), Norwegian vocalist Runhild Gammelsæter (Thorr's Hammer), and drummer Tim Wyskida (Khanate, Blind Idiot God). Their sole album, the dually-titled "Chaos Is My Name" / "Kaos er mitt navn," was released by Hydra Head Records in October 2006. Across eight Roman-numeral-titled pieces it alternates Gammelsæter's shrieked, free-form vocals with eerie ambient guitar and percussion soundscapes.

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.

Minnesota trio Worn Mantle emerged from an earlier, unnamed doom/post-metal project to craft sprawling, noise-caked blackened death/doom, stretching songs well past the 15-minute mark and drifting, per Decibel, into 'guitar-driven psychedelic ambience' between passages of black/death intensity and doom/sludge weight. Their self-titled 2022 debut and 2023 follow-up Hole have built them a quiet but attentive following in the deep underground doom scene.

Ecuadorian experimental collective from Guayaquil ('Psychedelic-Noise-Arkestra') led by multi-instrumentalist José Francisco Ycaza (aka Esquizoide 0nírico), billed 'Arkestra Director' in the Sun Ra tradition. Their 2019 album Nodvs Gordivs (Pensador Records) is a long-form concept piece weaving Castro, Alexander the Great and the Sabazios cult into a psychedelic doom/sludge/krautrock ritual built from extended pieces of noise, orchestral texture and heavy riffing.

Khanate was an American drone/extreme doom supergroup formed in New York in 2000 by guitarist Stephen O'Malley and bassist James Plotkin, with vocalist Alan Dubin and drummer Tim Wyskida. Their glacial music paired extremely slow tempos and harsh layers of feedback with Dubin's torturous shrieking, debuting with a self-titled album on Southern Lord Records in 2001. The band split in 2006 before a surprise return with the album To Be Cruel, released via Sacred Bones Records in 2023.

Emptiness are a Brussels avant-garde metal act formed in 1998 by bassist/vocalist Jérémie Bézier and guitarist Olivier J.L.W., both formerly of Enthroned (not in the E.M.M.A. atlas). Metal Archives tracks their evolution from Black/Death Metal in the early years toward Post-Metal/Post-Punk on later records, and their own bio describes the arc as moving 'through black and death metal, avant-garde experimentation, and claustrophobic minimalism.' Now signed to Season of Mist, their 2026 album Nowhere Speaks was tracked live in studio and deliberately loops back into the closing riff of 2014's Nothing But the Whole; the band also played Roadburn Redux 2021.

Owl is the Bonn, Germany atmospheric death-doom project of Christian Kolf (also of Valborg) and drummer Patrick Schroeder, running since 2010 as an outlet for the death-doom and funeral-doom territory Kolf's main band doesn't cover. Records like the self-titled 'Owl' (2011) and 'Nights in Distortion' (2018) split roughly evenly between churning, Immolation/Deathspell-Omega-tinged death metal and long ambient passages of shifting keyboards and reverbed guitar drone. Their most recent compilation, 'Grid Shimmer' (2022), was released jointly through Zeitgeister and Total Dissonance Worship, and they shared a 2019 split with Slovak act 0N0.

Burning Witch was an American doom/sludge metal band formed on Capitol Hill in Seattle in early 1995 from the ashes of the doom/death band Thorr's Hammer, active until 1998. Known for extremely slow tempos, dense feedback and Edgy 59's alternately mournful and tortured vocals, the group is best remembered as a formative pre-Sunn O))) project for guitarist Stephen O'Malley. Their EP recordings were gathered on the compilation Crippled Lucifer, released in 1998 on Southern Lord Records, the label O'Malley co-founded with fellow Seattle musician Greg Anderson.

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.
