Underground Metal Releases: Acausal Intrusion, Barrow Lord, and More

Mining Metal is a monthly column from Heavy Consequence contributing writers Langdon Hickman and Colin Dempsey. The focus is on noteworthy new music emerging from the non-mainstream metal scene, highlighting releases from small and independent labels — or even releases from unsigned acts.

One of the key drivers, I think, of proper extreme metal is conjuring precisely that blood-soaked and deranged psychedelia of the posters in the bedrooms of miscreants in the ’80s you’d see in certain slashers or cautionary films and TV shows. There was a certain sulfurous reek of evil to those images, like a head dripping blood or psychotic discontiguated human bodies arranged in a shocking Satanic tableau. It is an image-sense that is by its nature avant-garde because of how far it skews from both good taste and commonality, like an eruptive intrusion into the real by some outside force wielding black daggers and antlered at strange angels, crooked little demons of mud and bone and belching black smoke and torrents of vomit.

This is disjunct, obviously, from the real evils of the world. We are in an era where political consciousness seems as easy to gain as to lose, where nothing is apolitical anymore (and never truly was) but in turn can become a nightmarish mirror labyrinth attempting to navigate constructed arguments, falsified documents, and accounts from certain file dumps and live streams that beggars belief. The mystical and psychoactive evil of heavy metal is not, it turns out, evil at all, or at least evil in any objective criteria. It is pageantry, a cartoon, with the real evil out there sometimes happening so boldly in front of our faces it is staggering.

The evil of heavy metal, that necessary component, turns out to be reaction against the world. The reason so many youths indulge in acid trips and mushroom journeys is because there is in fact something out there that you can seemingly only witness for the first time via some aid unless your brain is wired just so. For some, the experience is so disorienting that their life seems either to fall apart around them or they become the kind of cold and sneering condescending pricks that look down their noses at the people around them. Heavy metal is a drug of that order, one that, handled properly, opens a door within you that says what you see around you does not have to be this way. There are realms of imagination, where common and good people can contain these terrifying surreal vistas like the plateaus of Leng or the frightening geometry of Kadath. It is a gore-soaked euphoria, part escape, sure, but also part manifestation in a very nearly Eat, Pray, Love sense of the term. It is a world of wild delight and one that the ardent metalhead strives to bring into their daily lives, an alien joy, an acid-burned smile.

Acausal Intrusion – Vomit Meditations

Opening a death metal record with piano is a bold move, especially when it skews more Angelo Badalamenti than traditional heavy metal styles. The music lurches in a Lynchian manner, like you are trapped in the Black Lodge and every shuffling, shambling step over those checkboard tiles brings you no closer to the looming doorway and only ever enfolds you deeper in the red drapes. It’s surreal music, one that starts at Gorguts and ventures further out into the avant-garde and bizarre black waters they touched on with Obscura before tightening their approach to control that chaos. Acausal Intrusion is as Lovecraftian as their band name implies, conjuring the same frightening and strange timbres of 2000s-era Mayhem in a death metal context. And it’s called Vomit Meditations to boot. I love death metal. Buy it on Bandcamp . – Langdon Hickman

Barrow Lord – Golgotha

We’ve covered Nocturnal Curse projects before . Ysbrydnos’ Welsh Mythical Darkness from this summer is one of the year’s finest black metal albums. Barrow Lord is another project from Ysbryd wherein they’re accompanied by vocalist Vass, whose higher register yelps sell Golgotha ’s vampiricism. Yes, this is wampyric black metal, meaning it’s all manner of rusty, tinny, and prickly, with synthesized flutes and dark ambient transitions rounding it out. Golgotha holds close the lessons of scrappy ‘90s Norwegian black metal with insight from France’s LLN regarding their recording quality and haunted overtones. But, Barrow Lord has trimmed the waste from both sources. The tracks are snappy and mystical, the fuzzy recording obscuring notes but not their impact. Barrow Lord are insular, inasmuch that this EP locks itself in the basement rather than exploring the entire residence, but that plays well into the “what goes bump in the night” atmosphere.

Cartilage – Operating Altar

It’s rare to hear a band the combines those first magical Atheist demos and records with deathgrind along the lines of early Carcass or Impetigo. Make no mistake: This is death metal through and through, but death metal of a certain vintage, from an era where hearing punky riffs next to a proggy brain-twister was de rigeur rather than a shock and where the brainy and the bestial were both doing their best to strike the other as gnarly . They’re not unwilling to shift into a total thrashing gear either, proving themselves nimble in their leaps from angle to angle without ever feeling disjointed. You’ll get a whiff of Rust -era Megadeth right next to something Possessed might have whipped out. It’s glorious. I love death metal. Buy it on Bandcamp . – Langdon Hickman

Fluisteraars – Jacht der Mysteriën

It’s little surprise that Fluisteraars are critical darlings. Emerging from a scene marked by its progressive and avant-garde interests in place of genre filial piety, the Dutch duo compose for thick-rimmed, well-read, sourdough-starting metalheads. They put black metal in an ecosystem where it can feed on the bacteria that other genres leave behind. That being said, their latest record, Jacht der Mysteriën, hones in on black metal’s repetition. It’s maximal minimalism, with singular riffs dominating each of the 10+ minute tracks, too energetic to be droning yet, by its own hand, one-note. Perhaps it’s because the intensity is kept so high that Jacht der Mysteriën never drags on despite itself. Fluisteraars are trying to hypnotize you. The tracks are indigestible logs, each commencing in media res and providing little denouement. As concentrated and prolonged exposure therapy, it’s a great dose of atmospheric black metal.

Miscreance – Reminiscence

There is a magical window whole fields of death metal aim for that lies precisely between Death’s Human and Cynic’s Focus . When you include the far more metallic work of Cynic’s early demos and Paul Masvidal’s appearance on a single Master record in the same window, you get a vision of heavy metal that is far too brutish and ugly to be the chrome-coated inhuman level of prog metal the more technical wings can sometimes become (said with delight, to be clear). Miscreance land an album dead center in this chunk of the death metal map, featuring soundscaping and melodic/harmonic movement that is far too brainy to be described as brutish while delivering it with a level of frantic energy that keeps it from feeling cold and overly calculated. The allowance of little slips and tiny gaffs is brilliant; it proves this is human work, something of passion and fire and not just construction. It’s fevered and alive. I love death metal.

Pakosteň – Spevy Smutných Lotrov

While punk and black metal constitute the largest portions of Pakosteň, sonically speaking, neither is embraced fully enough to define Spevy Smutných Lotrov . The Czech group’s latest EP transposes tremolo riffs and d-beat drumming onto punk rock’s group-oriented approach. Their power lies in their unity rather than composite parts. So, the lead riff on “Vavrín, Buchny, Pomyje” isn’t given a time to shine, and in that absence is something in-between Motörhead, Celtic Frost, and Discharge. If it feels detached, that’s before Pakosteň make it so, moving the focus from the individual to the group. Spevy Smutných Lotrov welcomes you into the fold despite its frosty presentation. What’s here is a pleasant inversion of blackened punk that wants you around, as opposed to misanthropy. That is, until you reach the title track, which may be the loneliest song released this month.

Sněť – V Bažinách Vědomí

This is not sophisticated music. Don’t misunderstand me: the players wield sophisticated musical language in a sophisticated way, communicating to a deft ear a level of control and deliberacy that marks true sophistication more than just rote technical ability. In summum, however, the result is something much more feral. I want to throw a chair through a wall or tear a tree out of the ground with my bare hands. I want to dig an enormous pit in my yard and then be inside of that pit. Their sound is deliberately gross , rotting off the bone, in a way that demonstrates their musical intellect to them is a tool and not the point. It is to transport you to disgusting realms of gut flora and walls of human intestines. What if King Crimson threw up all the time? I love death metal. Buy it on Bandcamp . – Langdon Hickman

unkindness – paraworld blue

From one half of Iron Firmament, whose debut In the Land of Pre-Human Kings crops up on every “best black metal of 2026” list or reel in existence, apparently, and from Wergild, the mysterious Washington black metal label that may just be three guys in a trench coat masquerading as multiple different bands, comes a fresh slice of cosmic horror, solitude, and raw black metal. On paraworld blue , unkindness tap into the loneliness that acts like Paysage d’Hiver exemplify to an even more pained extent. The solo project lashes between punchy and unadulterated black metal, down tempo and ambient, and post-rock from the ‘90s before the genre crystallized into crescendo slot machines. All this pairs with boldly misanthropic lyrics (standout being “ leave me alone ” from “sanctuary hologram”) that reflect a skepticism of everyone and the world. The turn is that unkindness demonstrate how isolating holding those fears can be. The coldness arises from pain and an attempt to dissect one’s own self-isolation. paraworld blue is moving music that searches for a meaning inside its own biases.
