Hexis: Copenhagen's Blackened Hardcore

There is a certain kind of Copenhagen band that treats the light rig as an enemy. Hexis are the purest example this city has produced. Formed around 2011, they have spent well over a decade dressed head to toe in black, faces greased into an anonymous smear that sits somewhere between corpse paint and a refusal to be photographed, playing a music that fuses hardcore’s velocity with black metal’s cold air and the crushing bottom-end of sludge. The term everyone reaches for is “blackened hardcore”, and for once the genre tag actually describes the sound instead of flattering it.

Understand the shape of the thing first. Hardcore, as a form, is fast, short, and built around the breakdown — the moment the tempo collapses and the room is invited to swing. Black metal runs on a different instinct: cold, atmospheric, tremolo-picked, more interested in dread than in release. Hexis weld the two so that a song can move from a blastbeat to a half-speed dirge inside eight bars, and the greased-black presentation tells you which side of the family they identify with when the lights finally come up. This is Danish extreme music with a Norwegian accent and an American engine.

A discography built out of splits

Most bands measure their career in albums. Hexis measure theirs in splits. The band’s catalogue is a sprawling web of shared 7-inches, EPs and collaborative releases with kindred acts across Europe and North America, a genuinely startling volume of physical output that dwarfs the three proper full-lengths. Those albums — Abalam in 2014, XI in 2018, and Aeon in 2023 — arrive rarely and land hard, but the true portrait of the band is in the flood of smaller records around them.

That release model is a philosophy as much as a habit. A split single is a low-stakes, high-frequency object: it keeps a band visible between albums, forces a working relationship with whoever shares the vinyl, and slots naturally into the merch box on a tour van’s floor. Hardcore has always worked this way, trading songs like correspondence, and Hexis import the practice wholesale into a sound that most metal bands would have tried to package into a glossy biennial album cycle. The result is a discography you assemble rather than simply own, scattered across dozens of small pressings that reward the kind of listener who follows a band down the rabbit hole.

The Latin and quasi-liturgical titling is deliberate. Abalam borrows the name of a demon; the tracks carry single-word Latin titles that function more like sigils than song names. It gives the catalogue the feel of a grimoire being written in instalments, which suits a band who withhold their faces and let the artwork — stark, monochrome, ecclesiastical — do the talking. The DIY infrastructure underneath all this matters as much as the riffs. Hexis have released through a shifting constellation of small labels and their own hands, the way a hardcore band does rather than the way a metal band does, and it has kept them free of the machinery that grinds heavier acts into a fixed release schedule.

The prolific split habit also tells you who Hexis run with. Sharing a record is a statement of alliance, and their collaborators map the exact European underground they belong to — the same touring circuit that carries Copenhagen’s other loud exports across the continent, the world I’ve written about in Little Country, Loud Export. Hexis are card-carrying members of that scene, and their splits are the receipts.

The live proposition: darkness as method

On record Hexis are punishing. Live they are a genuinely different animal, because the presentation becomes the point. The band favour near-total darkness, a single hard light or a strobe standing in for a full rig, and the black clothing means that for long stretches you are watching sound arrive from a void. It is theatre stripped to one idea, and the idea works because it is committed to absolutely.

The commitment extends past the lighting. Because no member is identifiable and no face is on the merchandise, a Hexis show has no frontman in the conventional sense — no between-song banter, no name-checking the city, none of the small human courtesies that most bands use to keep a room on side. What replaces them is pure atmosphere and volume, an unbroken forty minutes of dread that either grips you or loses you inside the first two songs. There is no middle setting.

Copenhagen’s small rooms were built for this. Loppen, Christiania’s loud little room, is the natural habitat — low ceiling, no barrier, a stage barely raised above the floor, the kind of space where a band who kill the lights can make sixty people feel genuinely uneasy. Stengade on Nørrebro does the same job with a slightly harder edge. These are the venues where blackened hardcore actually lives in this city, and Hexis have long been fixtures of that circuit, the sort of band the Copenhagen underground treats as its own even when they are away touring Germany for a month.

And they tour relentlessly. That is the other half of the Hexis method: a DIY European road schedule that runs on van diesel, floor sleeps and the split-release network, hitting squats and small clubs across Germany, the Low Countries, France and beyond. It is the unglamorous engine behind the mystique, and it is why a band who guard their identity so carefully are nonetheless one of the most-seen Danish extreme acts of their generation. The mythology and the graft are the same thing.

Where it sits in the Danish underground

Denmark punches absurdly above its weight in loud music, and the interesting thing about the current wave is how many distinct dialects it speaks. Hexis occupy the coldest, most austere corner. Turn one way and you find the cinematic, synth-drenched apocalypse of LLNN, the Danish sludge machine, who share Hexis’s taste for weight but chase grandeur rather than claustrophobia. Turn another and there is the shoegaze-lit black metal of Møl, who take the same tremolo language and drench it in melody and daylight. Hexis refuse both the grandeur and the prettiness. They stay in the dark.

The lineage runs back further than Copenhagen, of course. The blackened side of the sound owes its atmosphere to the early-1990s Norwegian second wave I’ve traced in Norwegian black metal, while the hardcore side descends from the Massachusetts metallic-hardcore tradition that Converge codified. Hexis stand at the exact junction of those two lines, which is a crowded corner internationally but a nearly empty one in Denmark. That is a large part of why they matter here: they claimed a specific sound early, held it for a decade, and made it recognisably Copenhagen. There is a wider point here about how a small national scene sustains a band this uncompromising. Denmark cannot support a full-time career in blackened hardcore on domestic gigs alone; the maths simply does not work in a country of under six million with a handful of suitable rooms. What keeps Hexis viable is the export circuit — the German squats, the Benelux clubs, the festival slots that treat a Copenhagen band as part of a pan-European underground rather than a novelty from the north. The split network is the passport. Every shared record with a French or American band is also a future tour booking, a floor to sleep on, a promoter who already knows the name. Seen that way, the prolific discography is an infrastructure rather than a quirk of taste, the thing that lets a band with no crossover ambition and no visible faces keep a thirteen-year career on the road. When the city’s DIY hardcore weekend, Vanguard Festival, maps the local scene, Hexis are one of the fixed points it is mapping around.

The sound up close

Get past the theatre and there is real craft in the writing. For all the density, Hexis are a band who understand exactly where to put the release. A typical track opens at full gallop, guitars tremolo-picked into a wall of grey, the drums locked to a blastbeat, and then — at the precise moment the ear starts to tire of the density — everything drops to a half-time crawl and the room lurches. That transition, the swing from black-metal saturation into hardcore’s stamping slow section, is the band’s signature move, and they deploy it with the timing of people who have watched thousands of rooms react to it.

The production choices reinforce the coldness. The guitar tone is trebly and abrasive rather than warm and scooped, closer to a Norwegian record than an American one, and the vocals sit high and shredded in the mix, a rasp rather than a bark. Low end comes from the rhythm section and the sheer volume rather than from a down-tuned crunch, which keeps the sound feeling thin and glacial even at its heaviest — a deliberate refusal of the comfortable, chest-warming weight that a sludge band like LLNN chases from the opposite direction. Hexis want you uncomfortable, and the mix is engineered to keep you there. It is a narrow palette, held with discipline across a decade, and the discipline is the achievement.

The case for and against

Blackened hardcore has a built-in ceiling, and Hexis run right up against it. The relentlessness that makes the band so effective for thirty-five minutes can flatten across a full album; when every song lives at the same pitch of dread, the dynamic range narrows, and the darkened-stage presentation that thrills in a sweatbox can read as a gimmick in a bigger room where the single-light trick loses its intimacy. These are the honest limits of the approach, and the band’s willingness to sit inside those limits rather than chase a crossover audience is either the whole appeal or the whole problem, depending on your appetite for punishment.

I land on the side of appeal, and the split-heavy discography is the reason. Hexis never asked to be a festival main-stage band. They built something smaller and more durable: a body of work released the way hardcore has always released, a live show that turns the absence of spectacle into the spectacle, and a genuinely uncompromising aesthetic held without a wobble for over a decade. In a scene increasingly happy to soften its edges for a bigger booking, that consistency reads as a kind of integrity.

If you want to meet them, do it in the dark. Find a Loppen or Stengade date, stand close, and let the room disappear. The record collection can wait — Hexis are a band you understand best when you cannot see them at all, which is precisely the effect they have spent thirteen years engineering. Copenhagen has louder exports and prettier ones. It has none more committed.
