The Fourth Sin, Overall Discussion

Opening Hymn — Descent Begins

Warren of Necrosis grabs you as soon as you hit play and drags you into a sinister story of sound, where thrash-fuelled speed and unbridled rage collide with crushing death metal in a blackened atmosphere.

Hymns as One — The Necrotic Tom

Warren of Necrosis offers more than four hymns — it unfurls an eighteen-minute descent that latches on and refuses release. Each hymn locks seamlessly into the next, twisting and bleeding together into a single, suffocating tale.

These hymns act like chapters in a grim tome carved into sound. The opening creeps in with rot and ruin, while each movement deepens the dread, layering decay upon decay. There are no fractures in the flow—riffs spill across boundaries, drums hammer without mercy, and guttural vocals crawl through every seam.

This setup turns raw hymns into a full plunge. For all eighteen minutes, the listener is pulled into the necrosis pit, swallowed whole. Few metal releases bind their songs this tightly; where most keep pieces separate, this work grips harder as a unified mass. When it finally releases you, the descent remains—its story etched deep in the mind.

The Unified Tale of Warren of Necrosis

Initium Finis — Genesis in Rot:Black Rabbit begins as a human priest, obsessed with divine favour. His sacrifices escalate from animals to humans, but his god rejects him. This downfall marks the first fracture: devotion curdles into corruption.

Apprehension — Pact at the Lake:Banished, he wanders through a wilderness of decay. At a black, ghostly lake, he meets a demonic entity. The pact forged here begins his physical and spiritual transformation — the priest becomes something darker.

Null and Void — The Necrotic Faith:Empowered, he manipulates followers to construct the Warren of Necrosis: endless tunnels of sacrifice and ritual. This is the birth of his own religion, hollow yet potent, a cult of decay.

Insurrection… Liberation — Apotheosis of Rot: Fully transformed into a demonic entity, Black Rabbit presides over the Tree of Eradication, fed by the souls of his victims. The warren becomes the centre of his power and corruption — liberation through necrosis.

Ritual Precision — Sound as Ceremony

Black Rabbit grips the listener with a devilmanship precision, executed with near-ritual perfection. Instrumentation, arrangement, and composition move as one—flawless in their cohesion—captured within a suffocating, cavernous atmosphere. Thrash metal lays the foundation, forming a rigid spine of speed and attack, while death metal supplies the crushing mass, all shrouded in a bleak, blackened haze.

The mix is raw yet controlled — clarity in the thrash riffing cuts sharply, death metal weight sinks deep and oppressive. Mastering preserves the violence without sanding down the edges — the aggression remains intact, favouring atmosphere over sterile polish.

Warren of Necrosis feels like a slow descent into decay. Thrash rhythms quicken the pulse, death metal thickens the flesh, and blackened shadows darken every corner. The production rejects false gloss by design, keeping its feral edge intact. The sound mirrors the ritualistic dread of the lyrics, dragging the listener into the pit. No shine conceals the rot—only a pure, unrelenting metal storm.

Blades of Corruption — Strings, Pulse, & Thunder

Instrumental forces Jelle and Hidde—dual blades of corruption—tear through the hymns with serrated guitars. Unleashing fast, palm-muted riffs gallop forward as razor-edged downstrokes drive the aggression.

Their devilmanship cuts deeper with low-tuned chugging and crushing breakdowns, adding immense weight, while blackened, dissonant tremolo passages and eerie chord voicings summon a ritualistic dread.The solos are chaotic yet controlled — shrieking bends and rapid-fire runs that feel less like leads and more incantations spat into the void.

Thijs Mulder’s bass swells thick and distorted, its growl anchoring the low end like a living force. Often shadowing the guitars, his lines double the impact and deepen the mass — no thin resonance, only iron weight locked tight beneath the riffs.

Behind it all, Koen van der Voet batters the kit like a rabbit’s foot possessed, forging the heartbeat of rebellion. Double-time assaults drive the charge, snare cracks snap like gunfire, and death metal power blasts surge through relentless double-kick barrages. His crushing tom fills roll like distant thunder, smashing transitions and keeping the momentum vicious and unbroken.

Scripture of Decay — Vocals as Rite

Nino Thomas delivers vocals that sound like scripture carved from decay. His voice mutates seamlessly — from raw, venomous thrash barks to cavern-deep death growls — while blackened shrieks cut through the haze like ritual blades, sharpening the EP’s dark narratives.

His approach shifts with the unfolding storyline. On Initium Finis, he commands like an unholy priest, resolute and domineering. Apprehension trembles with panic and desperation, his voice cracking, and straining in its menace. Null and Void becomes a sly, corrupted sermon, seductive in its menace. By Insurrection… Liberation, the mask is torn away — demonic roars erupt in a final purge of rage and release.

Throughout, Nino chants as if bound to some forgotten rite. Lines roll forward like blasphemous sermons, each word measured and deliberate, as though he’s reciting verses of rot and ruin pulled from a decaying scripture.

Cavernous Atmosphere — Tombs of Sound

Warren of Necrosisconstructs a suffocating moodas dense as the riffs themselves. Subtle layers of reverb wash over every sound, deep and lingering, while the cavernous mix drags the listener underground — into tombs, crypts and hidden labyrinths where decay hangs thick in the air.

Feedback hums beneath the surface, and sustained chords drone with slow, deliberate intent. They move like ritual chants, pulsing with the rhythm of heartbeats long buried. This sonic space amplifies the theme of rot and ruin, sealing the listener inside an unlit world of gloom.

Necrotic Benediction — Final Blow

In the end, Warren of Necrosis lands as a brutal, uncompromising strike. This release stands as a ferocious fruit of art, a raw force that seizes the listener and refuses mercy. Each hymn seethes with necrotic energy, leaving nothing untouched—only ruin, resonance, and brutality that lingers long after the final echo fades.

Rite — Insurrection… Liberation

The album closes with Insurrection… Liberation. The music falls silent, but the story refuses to end — it lingers, unresolved, echoing in the aftermath of decay and defiance. What remains is not closure, but consequence: the Warren stands, the transformation complete.

The Fifth Sin, The Memorabilia

For me, Warren of Necrosis is more than a release — it is brutal storytelling carved into sound. The four hymns unfold as one necrotic parable: a priest’s downfall, a pact at the lake, the hollow birth of the Warren, and the final apotheosis beneath the Tree of Eradication.

Listening feels less like consuming music and more like entering scripture — each riff a blade, each growl a sermon.

What struck me most was how vividly the story bled into vision. As the hymns played, I pictured the descent as if it were an animated nightmare — a necrotic counterpart to Watership Down. Both film and EP twist innocence into violence, burrows into labyrinths of death, and survival into corruption. The music becomes a perfect soundtrack to that imagery: relentless, cinematic, and merciless.

The only lament is its brevity. Four hymns are enough to scar, but not enough to satisfy. The Warren demands return — dragging me back down the rabbit hole for another immersion in extreme rabbit metal.

The Sixth Sin, The Artwork

The artwork is not merely artwork — it is the storyboard.

The Seventh Sin, Disrelish

There is nothing to dislike within the musical offerings of Warren of Necrosis. Black Rabbit deliver a release forged with intent, cohesion, and devilmanship, leaving no space for excess or hesitation. This EP stands as a complete descent — uncompromising, immersive, and brutal in both sound and vision. Warren of Necrosis does not ask for attention; it demands return.
