SLAGMAUR – Hulders Ritual

I am, once again, being bullied by chronology.

 

Fortress Festival 2026 is done and over. I have written the prequel. The travel bit. The England bit. The sea-view swooning, weather confusion, beans on toast, sunburn, tourist-related misanthropy, and accidental Dracula acquisition.

 

All very important festival groundwork, obviously. I ended that piece with “continue reading…”

Because I felt very motivated and had the best intentions.

There are two more parts to follow. The actual festival parts. The music. The bands. The vibe. The thing people probably came here for in the first place.

 

Tiny problem.

I have not written those yet.

Because once again I got sidelined by my own brain. It saw a perfectly reasonable linear timeline, took one look at it, and went: Absolutely not. Let’s split into 200 side quests instead.

 

So now things are overtaking themselves. Again. I haven’t even finished typing up Fortress Festival 2026, and Fortress has already gone ahead and dropped the first wave of band announcements for 2027.

 

Great.

Just great.

Add to the homework pile, why don’t you.

 

Obviously I am going to dive into each band. Obviously Fortress has once again managed to pick names I either barely know or have not heard of at all. Obviously I am excited, because by now I know there will be gems hidden in that line-up I probably would not have found this quickly on my own.

 

So yes.

My brain is already opening spreadsheets.

 

But—to my genuine delight—we can actually tick one band off the to-do list already.
And not just any band. The Ocean Room headliner.

 

I am talking about Norwegian avant-garde black metal collective Slagmaur and their latest album Hulders Ritual, which I reviewed for Stormbringer back in February 2026.

     

And since Slagmaur are now officially part of the Fortress Festival 2027 line-up with a freshly announced UK exclusive performance, this feels like the perfect moment to bring that review over here and kick off the Fortress ’27 preparation series.

 

Even though I have not finished the Fortress ’26 recap yet.

Oh well. Details.

 

My brain does not work linearly. It works on excitement.

And right now, this announcement has me hopping up and down with joyful glee like a woman who has just been handed a fresh excuse to abandon all sensible priorities.

So. Hulders Ritual. Released on 27 February 2026 via Prophecy Productions.

 

I picked this one up for review because I was immediately in love with the cover art. Don’t know why.

Well. That’s a lie. It was the sheep. I loved the sheep. Went for it. Full stop. I am easy sometimes.

 

So I got the promo, clicked play on Huldergeist, and—well. A lot of things happened in my mind. Not all of them good. 

Vocals here come from D.G. of Misþyrming and Hoest of Taake. The whole thing sits somewhere between irritation and fascination.

 

Slagmaur are testing how much reduction you can take before they tighten the screw: tempo hiccups, nervous breaks, more unrest inside the structure. Towards the end, Norwegian folk vocal passages suddenly appear—unexpected, and at the same time strangely logical within the whole hulder album theme.

 

The track lasts eight minutes. Eight minutes that either hypnotise you or give you a headache, depending on the day. 

After Huldergeist, I wasn’t sold yet. I was still not sure whether this was going to be my album.

And then Hexen Herjer came on, and it was just stupidly fun.

In an insistent, slightly unsettling way, the song is hypnotic. Like a snake following the flute, you follow the beat. The trick is, once again, repetition: the same pattern, again and again. Your brain reaches for it and then just stays there willingly, like an idiot.

 

And in between, the forest fully loses its mind. Screaming, barking, growling, general madness noises—all thrown over a wall of dense distortion. Absolute avant-garde shenanigans. I was grinning, shaking my head, and having the best time.

 

Fantastic.

If you are only going to play one song from this album, make it this one.

And then the rabbit hole opened.

Sitting at my desk, suspiciously invested, opening tabs like a woman pretending she had not just clicked on the promo because of sheep and then got rewarded with forest barking, I did the homework.

Hulder. Folklore. Band background. The whole little research spiral.

 

Let’s talk about "hulder" for a second. Because we all know Hulder as a black metal band that photographs really well. But a hulder is also a spirit from Scandinavian folklore. A forest being, often described as beautiful, peaceful, and benevolent.

 

Norway, however, also knows the less idyllic versions. Men who fail to please them get killed. Children are stolen and replaced with the hulder’s own malformed offspring.

 

With that in mind, the title Hulders Ritual immediately sends the brain straight into Norwegian woodland territory. Fog between the fir trees. Something calling from deeper in. Something pretty enough to follow.

Not creepy at all.

 

And while I was researching, I realised Slagmaur had not simply taken the hulder theme, slapped it on the cover, and wandered off.

No.

That would have been far too normal.

Folklore was not just background flavour here. They built the entire release around it.

And they took their sweet time doing so.

Hulders Ritual is Slagmaur’s fourth studio album. It came nine years after their last studio album, Thill Smitts Terror.

Nine years that, according to the band, were not spent dillydallying.

Two singles had already been thrown into the world years earlier, seemingly without much context: the raw, frostbitten Wildkatze in 2019 and the driven, punkish Ritual Dogs in 2022.

 

And all this time, in the background, a very carefully planned promotional campaign was apparently taking shape.

 

In November 2025, Norwegian media reported that General Gribbsphiiser and Thorns mastermind Snorre W. Ruch had gone missing after a men’s hike in the Varghiet area.

 I do admire a man who undersells.

 

What we got was a staged true-crime narrative as an extension of the album’s theme around "bergtatt"—being taken into the mountain, abducted by mystical beings.

 

Concept as full experience.

Ritual as marketing.

Marketing as ritual.

You can call it megalomaniac.

You can call it consistent.

What you cannot call Slagmaur is half-arsed.

Musically, the whole album works through insistence. Repetition is weaponised.

 

Motifs are repeated until they either burn themselves into your brain or you surrender voluntarily. Sometimes it is exhausting. And that is almost certainly the point.

 

You feel that across the whole album, not just in Huldergeist and Hexen Herjer.

 

Warlock gives me slight Dimmu Borgir vibes—even though Silenoz only appears on the next track—but less symphonic, more industrial. The vocals are deeper here, more growled than before, the drumming slower and heavier. The whole thing feels denser. More threatening.

 

Rathkings, meanwhile, pulls the industrial elements back and leans harder into black metal. Blast beats, shimmering guitars, venomous shrieking. Rawer. More aggressive. Less hypnotic. Probably the most traditionally black-metal-heavy track on the album. Towards the end, it takes a brief orchestral detour into horror soundtrack territory, because why the hell not.

 

There is a lot happening here.

And if you are not listening closely, it can blur into noise very quickly.

Ultimately, Hulders Ritual works on two levels.

 

Musically, the album weaves together industrial elements, lo-fi aesthetics, and classic Norwegian black metal without Slagmaur disappearing completely into avant-garde fog. The melodies land. The repetition is not accidental. It is the method.

 

And then there is the staging.

The missing-person story. The "greatest social experiment". The grand concept. A lot of black metal theatre. A lot of self-mythologising. A lot of confidence.

 

Too much self-love?

Maybe.

A touch of elitism?

Absolutely.

 

Whether you call it art or overkill is, in the end, up to you.

 

But here is the fact: Slagmaur live at Fortress Festival 2027?

I expect proper black metal theatre.

No half-measures. No pulling punches. 

If you build the whole thing like a ritual, you better bring the ritual.

I can't wait to see what happens.
