Thy Sanatorium formed in 2025 as an anonymous, multi-national collective working in the space where black metal pressure, gothic shadow, symphonic weight, and flashes of melodic death all sit in the same room.
Their third single, “No Flag Left To Burn,” landed on 30 January 2026 as a self-released digital track, backed by an official video, recorded at The Sanatorium and produced, mixed, and mastered by Aries, who also answers the interview below. Earlier singles leaned into horror in the more traditional sense. This one points the lens at war, and what it does to people who never chose it.
“One of our band members is from Algeria, and that’s all I will say.”
You describe Thy Sanatorium as an anonymous multi-national collective. What does anonymity protect for you, and what does it allow you to do creatively?
Aries: It protects the freedom to be whoever we want to be, with total creative freedom, while adding an aura of mystery to the whole experience. Thy Sanatorium can be anyone, and creatively that allows us to draw inspiration from different places and blend different elements without being labelled as just one thing.
When you write under that horror focus, what are you trying to evoke in the listener beyond “dark” aesthetics?
Horror is different for everyone and covers a wide range of things. The song “Torment” is the perfect example. What torments you? It can be anything: an upcoming school test, a doctor’s appointment, a work meeting, an annoying neighbour, a person in your life… anything that causes anxiety becomes torment. And how do you deal with it?
“The End Consumes” is about living life to the fullest, because death is coming and it can be unexpected. It’s really about memento mori, and living in the moment. While horror often has fantasy elements, it comes from reality. Ironically, our songs often come from a positive place… but we give them a Thy Sanatorium treatment.
“I’ve personally had the experience of being in a war zone. I’ve seen the devastation and the desperation it brings to innocent people.”
“No Flag Left To Burn” is a strong title. What does it mean, and what pushed you to release this song now?
I’ve personally had the experience of being in a war zone. I’ve seen the devastation and the desperation it brings to innocent people. What is a flag without its people?
How can anyone claim to be a winner if, in order to win, they had to kill children? That’s the meaning behind “No Flag Left To Burn.” There is no “good side” if the innocent are dying in the process. There is no winning.
It’s a very real horror we see daily all over the world. The release timing had nothing to do with current events. It just felt like a natural release after the first two singles. Sadly, no matter when we released “No Flag Left To Burn,” it would still be relevant because of human nature.
What part of Thy Sanatorium’s sound is non-negotiable when you’re building a track from scratch?
We approach each song like it could be the opener of the album. You’ll hear this when the album comes out. Just when you expect something more mid-paced, or a ballad, you get hit with something equally powerful, or even more so.
With the exception of one very beautiful piece composed by Remus (our pianist and keyboard player), which serves as a build-up to the final song on the album, every track is treated like it should hit hard. As a result, there are no filler songs.
“A musician is like a chef creating a menu of different dishes.”
You’re blending black metal with gothic and symphonic elements. What makes it feel like one world instead of separate ingredients?
I think our collective sound is what glues it together. It just works. Music is like food and art. A musician is like a chef creating a menu of different dishes, while still making it a cohesive experience. A painter chooses different colours and styles for different paintings. Thy Sanatorium draws from different things too — from subgenres to cultural elements — and it becomes one world.
With multiple members handling vocals, what’s the logic behind how you use different voices across a song?
Ra is the lead singer for about 80% of the upcoming album, with his powerful death/black metal voice. You’ve heard Crux on “The End Consumes,” duetting with Ra, and she also leads a song on the album called “Devil’s Heart,” plus duets on other tracks.
Nyx and I are mostly backing vocals, supporting Ra and Crux, but Nyx also did the creepy spoken parts in the pre-choruses on “Torment.”
Nothing is usually pre-determined. It’s more like, while we’re writing, someone says, “Crux or Nyx should double this part,” and it evolves naturally from there.
Keys and piano can either lift a black metal track or drown it. How do you decide when the keys lead and when they stay in the shadows?
Piano and keys are an integral part of Thy Sanatorium’s sound, and Remus is a master at doing what the song needs without overdoing it.
Too much salt can ruin a dish, but the right amount can make it amazing. When I mix, I approach all instruments as an ensemble that tells a story. Even with guitars, I think more like a producer than a guitarist. I want them to blend, not overpower everything else.
I spend hours mixing because our songs are dense. For example, Crux recorded 24 vocal tracks for her parts on “The End Consumes,” and she isn’t even the lead singer on that song. So there’s a lot of attention to detail.
I also love the idea that, if you pay attention, you’ll hear something new each time. There are hidden things you won’t notice unless you listen closely. It’s cinematic in that sense. I love movies where repeated viewings reveal new details, and I enjoy doing the same with music.
“There are hidden things you won’t notice unless you listen closely. It’s cinematic in that sense.”
You formed in 2025 and you’re already close to a debut album. What did you learn in that first year that changed the way you write now?
“Torment” was written before Thy Sanatorium even existed. It took over a year before Ra and I connected, and we instantly had a creative chemistry. From there, everything fell into place as other members joined.
We wrote, recorded, and released “The End Consumes” in less than a month, and that’s when we decided to make a full album.
What’s evolving is that we’re getting to know each other more creatively, and that’s bringing new elements into the music. While I write most of it, each member contributes with total freedom and gets to be themselves. I think that brings out the best in everyone, and it’s a big part of what makes Thy Sanatorium unique.
You’re in the final recording stage, with mixing/mastering still ahead. What are you most protective of as you move into that final phase?
My sanity. I have so much to mix over the next three or four weeks. A few things still need to be re-recorded, but that will be quick. The mixing is the massive task, and I’ll need my own Thy Sanatorium treatment after it’s done.
Other than that, we’re just excited to get more music out there and see how people respond. So far, the reaction has been beyond our expectations.
What does “multi-national” mean in practical terms for the band: how you work, how you share files, how decisions get made, how you stay tight?
It usually starts with a demo or rough draft of a song idea. We discuss the theme of the song and take it from there. We usually have a finished demo within a week, then we fine-tune recordings for release. It’s all remote.
As for decisions and staying tight, we put our egos aside and do what’s best for the collective. It also shows that six individuals from completely different cultures and backgrounds can come together and do something like this.
We respect each other, regardless of differences and disagreements. Maybe some people will take note of that and be inspired to do the same.
What do you want the debut album to achieve?
We’re approaching the album the same way we started Thy Sanatorium: with zero expectations, and seeing what happens.
When we released “Torment,” it got positive reviews and a lot of people seemed to enjoy it. “The End Consumes” doubled that. “No Flag Left To Burn” seems to have solidified a lot of things, and more people are taking notice. We’ve been getting a lot of interest, so we’ll see where it goes.
When you say “multi-national,” is there any African or African-diaspora background in the band — and are there any African bands or scenes you already follow?
Yes. One of our band members is from Algeria, and that’s all I will say. I don’t want to take away the fun from anyone who wants to try and find out who we are. If the band continues to grow, eventually it will come out, but for now the mystery is part of it.
I’ll be honest: I wasn’t very familiar with African metal, but that’s changing. I’m starting to discover a lot of great bands.
