with their heaviest and most heartfelt offering

Unverkalt - Oath Ov Prometheus (Official Music Video)

While still possessed by a cinematic vision, Unverkalt are throwing back the velvet curtain in favor of the veil. On their upcoming third album and first since signing with Season of Mist, the post-metal luminaries plunge into the darkness that awaits us all. Héréditaire now stands as their heaviest and most heartfelt offering.

“…gothy, doomy, ethereal”, Brooklyn Vegan wrote in describing the album’s lead single “Die Auslöschung”.

Today, Unverkalt are releasing the second advanced single from Héréditaire.  While it sets fire to the myth of man’s creation, “Oath Ov Prometheus” is ignited by the band’s newly blackened spark.

“This song reflects on the illusion of greatness, how humanity crowns itself as a god to preserve its place at any cost”, Unverkalt says. “Not all who swear, serve the light. Some carry fire only to burn”.

Vocalist Dimitra Kalavrezou remains one of Unverkalt’s unmistakable traits. Her clean singing twists above the band’s fiery new single with all the mystifying beauty of a phoenix from the ashes. But as the first song written for Héréditaire, “Oath Ov Prometheus” reveals a haunting new depth to her voice.

“I encouraged her every day to go further with her vocals.”, Unverkalt’s guitarist and primary composer Themis Ioannou says with an appreciative smile. “But the progression of our music came naturally. We love to experiment with every album. With Héréditaire, we wanted to introduce extreme vocals because they bring out all these heavy feelings. It’s like they’re shaking you awake”.

Héréditaire is a pulse-pounding new direction for Unverkalt. Stoked by blast beats, smoky post-metal atmosphere and headbanging doom, “Oath Ov Prometheus” rages with righteous fury. Where the band’s previous two studio ventures took cues from French painting and European film noir, their upcoming album traces back to mankind’s deepest and darkest origins. With each blackened scream, its new single dismantles the myth of god’s perfect creation.

“‘Oath Ov Prometheus” speaks of the moral collapse of a future set ablaze in a world intoxicated by power”, Kalavrezou says, “where control is placed above all else, no matter the cost”.

“I enjoy discovering new, unique and compelling music in today’s overwhelming world of information, and I believe I truly succeeded with Unverkalt”, says Season of Mist labelmate and Rotting Christ frontman Sakis Tolis, who’s featured on the monolithic “I, The Deceit” from Héréditaire. “This is an exceptional piece of art, worth every minute of listening”.

The video for “Oath Ov Prometheus” was produced by Unverkalt and directed by Themis Ioannou at RAWBITE Studio.

UNVERKALT are drawn to the edge. Since emerging from the underground, the Germany by way of Greece post-metal band have balanced boundless atmosphere with suffocating heaviness. Their third album and first since signing with Season of Mist doesn’t continue in that direction so much as it plunges into the darkness that’s always been waiting below. Héréditaire lifts the veil from our cursed existence. What emerges is Unverkalt’s heaviest and most heartfelt offering.

“Our aim has always been to blend softer, more romantic elements with extreme chaos. With Héréditaire that time has now come”, says the band’s guitarist and chief composer Themis Ioannou. “This album is a lament for what is far older than our very existence. It speaks of what seeps through generations, searching for an answer to one pervasive question: What do we carry that was never ours?”

From the beginning, Unverkalt was born from an urge to give life to grief. In 2017, Ioannou started the band with vocalist Dimitra Kalavrezou in hopes of creating something that was slow-burning and visceral, crushing yet delicate. Their debut made good on that promise: “...so rivetingly beautiful that you will have to deepen to digest it”, Metal Hammer Greece wrote in awe of L’Origine du Monde. “Easily on the top-10 of 2020”.

The band’s second album followed three years later to further acclaim. While swooning between obsession and annihilation, A Lump of Death: A Chaos of Dead Lovers sharpened Unverkalt’s vision by pushing their avant-garde streak with more force. “Beyond being able to point roughly towards a couple of different genres, it is utterly impossible to compare them to any other artist out there making music in the same vein”,  The Sleeping Shaman admired. Echoes and Dust agreed: “It stands in its own right as a beautiful slice of filmic post-rock, a soundtrack without a movie beyond the one playing in your head”.

Héréditaire is still possessed by cinematic visions. Like a camera coming into focus, lead single “Die Auslöschung” appears through a thickening haze before it’s snapped out of a trance by drummer Christian Eggers’ fiery blast beats. The album shifts between colors, textures, even languages. Stirred by a mournful saw of strings, “Ænae Lithi” raises memories of the Great Fire of Smyrna that were handed down by Themis’ grandmother. But where previous albums took cues from French painting and European film noir, this one throws back the velvet curtain in favor a veil. “Oath Ov Prometheus” dismantles the myth of man as god's perfect creation with Kalavrezou’s freshly blackened vocals.

“We love to experiment with every album”, Ioannou says. “With Héréditaire, we wanted to introduce extreme vocals because they bring out all these heavy feelings. It’s like they’re shaking you awake”.
While Héréditaire is a pulse-pounding new direction for Unverkalt, the album’s arc traces back to our deepest and darkest origins. Amidst the tremolo-picked wreckage of “Penumbrian Lament”, long-held beliefs are swallowed into the void of guitarist Eli Mavrychev’s death growls. “It’s all sorts of dead ideas / They cling to us all the same”, Kalavrezou whispers, only to break into screams on “Introjects” beneath Joscha Hoyer’s throbbing bass line. “The concept behind the record is tied in with the album’s overall heaviness”, she says. “Each song peels back another blackened layer of memory, trauma and suffering, which linger over us like ghosts: invisible, yet endlessly present”.

Kalavrezou’s mystifying cleans remain one of Unverkalt’s defining traits. Even when trembling beneath the monolithic riff of “I, The Deceit”, her contempt for those who stand by as the world burns is heated when forged alongside her Athenian brother-in-arms Sakis Tolis from Rotting Christ. But as the album draws to a close, Héréditaire ends shadowed in doubt for the future. “Bathed in lies / Can we make it better” she wonders before disappearing into the shivering wake left by “Maladie de ‘Esprit”.

“This album is not meant to resolve”, the band says, “but to dissolve patterns from those who came before, faceless yet familiar. The colors have drained. What remains is veiled in black, not as a symbol, but as a truth that covers everything”.

On Héréditaire, Unverkalt lift the veil on our cursed existence with their heaviest and most heartfelt offering.
