After festering in their hallowed crypt for the past eight years, finally, Spawn of Possession are reborn as RETROMORPHOSIS. Once again, Jonas Bryssling and his former bandmates joined forces with ex-Obscura and Necrophagist guitarist Christian Muenzner. But in adding former Decrepit Birth drummer KC Howard, along with some old-school bells and whistles, this new band of proven players has unlocked the missing link in technical death metal’s evolutionary chain.    

“My issue with modern tech bands is they forget they’re a death metal band“, Technical Music Review writes in their review of Retromorphosis’ debut album Psalmus Mortis. “Retro has plenty of groovy, heavy ass riffs that punch you in the face”.

Psalmus Mortis was released yesterday, Friday, February 21 on Season of Mist. You can hear all eight exquisitely ugly songs by listening to the full album stream on the Season of Mist YouTube channel.

Psalmus Mortis is nearly a decade in the making, but Retromorphosis’ debut album shows that this band loom over technical death metal larger than ever. Lead single “Vanished” comes screeching out the shadows before quickly settling into a bone-crunching riff that reeks of the old school. 

“I prefer my death metal to sound ugly and mean” axeman Jonas Bryssling says with a satisfied grin. 

For Psalmus Mortis, Retromorphosis reunited with fellow Swede Magnus Sedenberg, who’s been their preferred engineer of death since Spawn of Possession’s first two demos. But this time around, they opted for more of the raw production that defined the scene during the early ’90s. Caspersen’s fast and filthy bass runs are the gnarled roots from which the twisted tale of “The Tree” takes its accursed hold. 

“There was no hesitation”, Bryssling says about respawning with his old bandmates. “I don’t have to tell them much. They know how it’s done”.

Given this band is blessed with ungodly levels of technical skill, it’s no wonder that Retromorphosis have concocted some freshly freakish experiments. Psalmus Mortis opens with spooky organ glows, tense strings and a ghostly gothic choir. “That sense of atmosphere is something that old-school bands used to have”, Bryssling remembers. “I really like that. The organ is my favorite instrument. I just kept adding it to every song”.   

Evil atmosphere isn’t the only new life force on Psalmus Mortis. “Everyone knows KC Howard is an insane talent”, Bryssling says about his new drummer. Howard left his brutally precise mark on the scene when he was behind the kit for Decrepit Birth, but he’s the radioactive ooze that feeds Retromorphosis’ frenzied nucleus. His non-stop nuclear barrage drives high-flying album closer “Exalted Splendour” toward its blinding conclusion.

“We had rules in Spawn of Possession”, Bryssling explains when asked what separates Retromorphosis from his previous offspring. “Everything had to always be so intense. Retromorphosis is more free. Psalmus Mortis can be eerie, doomy or even quite simple”.

Put the song that bears their name under the microscope and feast your eyes on everything Retromorphosis are capable of. Christian Muenzner rips through not one, not two, but three guitar solos, each one packed with more technically innovative twists than a triple helix. “I’m the one / chosen son / gifted and reborn“, vocalist Dennis Röndum growls like a man newly possessed by the devil.

Even a lawless field like death metal has exceptions that prove the rule. Retromorphosis spawned from a unique leader of the genre, but their unholy union on Psalmus Mortis is a living testament that you can’t bury what was already undead. 

Spawn of Possession remains one of modern metal’s most accursed influencers. During the early to mid-2000s, the noctambulant Swedes toured both sides of the Atlantic alongside Cannibal Corpse and Hypocrisy. Having scaled the accursed summit to reach death metal nirvana on what was only their third album, after three decades, the band was put to rest. But like an especially pungent spore, the seeds of SoP have been festering in its hallowed crypt, waiting to come alive and haunt the earth once more.  

Such is the sordid backstory of Retromorphosis and their debut Psalmus Mortis. In 2020, amidst the pandemic’s endless lull, one of Spawn of Possession’s founding members was again bitten by death metal’s radioactive songwriting bug. “I wanted to make an album that wasn’t tied to anything we’d done before”, says Jonas Bryssling. While this new batch of malevolent creations still stemmed from his punishingly technical fretwork, the riffs were splitting off into even more twisted headbanging directions. But to bring these relentless mutations to life, first, he needed a familiar spark.   

“There was no hesitation”, Bryssling says when asked about resurrecting the creative energies with his former Spawn of Possession bandmates. Pairing back up with rock-solid vocalist Dennis Röndum and elastic bassist Erlend Casperson once again yielded promising results during the early phases of Psalmus Mortis. To further test the equation, they added another familiar but no less fearsome shredder. Before joining them for Incurso, Christian Muenzner lent his flaming left hand to two other stone-cold classics: Necrophagist’s Epitath and Cosmogenesis by Obscura. “I don’t have to tell them much”, Bryssling continues. “They know how it’s done”. 

Indeed, time has only fermented this group’s mutant chemistry. After spending the summer of 2023 recording Psalmus Mortis in their underground laboratory, Retromorphosis emerged with the missing link in technical death metal’s evolutionary chain. “Vanished” officially cracks open its beaker with the satisfying crunch of the old school, steamrolling out a rugged red carpet for Röndum’s imposing growl. It was the first song Bryssling wrote during the album’s initial trial period, but the band continued to tinker with the album’s eventual lead single after the other eight tracks were hammered into gruesome shape. Muenzner’s solos scream like a poor unsuspecting soul who’s being dragged into the shadows. All the while, Casperson flogs his bass as if hiding a mischievous grin, its ghoulish bounce bringing the lyrics’ cosmic body horror into frightening focus.  

“We had rules in Spawn of Possession”, Bryssling explains, as a matter of fact. “Everything always had to be so intense. Psalmus Mortis is intense, too, but it can also be eerie or even quite simple”.  

Simplicity might not be Retromorphosis’ dominant chromosome. Even though it’s fueled by straight-forward, down-picked chugging, the album’s nine-minute monolith “Machine” churns through multiple tempo changes, cranking up the tension with every accelerated blast beat. But the band did opt for a leaner chemical base. Psalmus Mortis was produced by Magnus Sedenberg, who’s been the band’s Swedish engineer du jour dating back to Spawn of Possession’s first two demos. “Reuniting with Magnus felt like the natural thing to do”, says Bryssling, “but for this album, we scraped away some of the studio polish”. With its sludgy distortion and hallucinating speed, “Never to Awake” certainly summons the ’90s untamed spirit. “I prefer my death metal to sound ugly and mean”.

While roughly a decade in the making, Retromorphosis still grip it and rip it on Psalmus Mortis. Heck, chunks of the band’s first album were hung up to dry like butchered livestock after just one crack in the studio, much to their own amusement. “I don’t think there’s a single first take on the SoP albums”, Bryssling laughs. Röndum doesn’t mince words, either. He chews through syllables with all the careful consideration of a meat grinder. And while each tale descends into its own sweaty night terror, they all escalate from bad to worse. Despite its seemingly pedestrian title, “Aunt Christie’s Will” unpacks a maze-like mystery that ends with an especially morbid twist.

Of course, given this crew’s technical chops, Retromorphosis were bound to birth more head-spinning experiments. Psalmus Mortis injects fresh blood into their chilling cosmic horrors by fleshing out their technical arsenal with some unusual instruments of torture. The album opens with doomed power chords, pounding drum fills, then…spooky organ glows, tense strings and a ghostly gothic choir. “That was a new experience”, Bryssling says about adding more synthetic textures to the mix, though his inspiration came from a life-long obsession. “That sense of atmosphere was something old-school bands used to have”. The special effects aren’t just saved for its ominous opening instrumental oeuvre, either. “The Tree” puts a dystopian twist on the age-old tale of human greed with synths that glow like alien guts. 

Freakier ambience isn’t the only new life form on Psalmus Mortis. “Everyone knows KC Howard is an insane talent”, Bryssling says. Howard left his brutally precise mark on the scene when he was behind the kit for Decrepit Birth, though Retromorphosis were formally introduced to their new drummer through Röndum, as the two had crossed paths during an episode of the Cali Death Podcast. Howard’s nuclear barrage of double bass kicks feeds the band’s cellular engine like jet fuel, driving high-flying album closer “Exalted Splendour” toward its blinding conclusion.  

Ask Bryssling to identify what separates this new baby from their first born and the answer is, in fact, quite simple.”Retromorphosis is more free”. Put the song that bears their name under the microscope and feast your eyes on everything this band are capable of: non-stop blasting, brain-bursting bass fills, solos that would fry a supercomputer and pure unholiness. “I’m the one / chosen son / gifted and reborn”.  

With Psalmus Mortis, technical death metal’s chosen ones rise from the grave.

Eight years ago, the underground lost a unique leader when Spawn of Possession crawled into their hallowed crypt. Foul-mouthed disciples still utter the name SoP with reverence, but while others tried to crack the band’s forbidden cabinet, these accursed innovators were secretly festering in their grave, plotting to return and haunt the world of extreme metal once more. 

Now, the undead masses can finally rejoice. Thanks to a healthy kick from their decrepit new drummer, Spawn of Possession has been reborn as Retromorphosis. With their debut album, this new band of freakish players emerge with the missing link in technical death metal’s evolutionary chain. The latest mutation off Psalmus Mortis is a living testament to their ungodly strength. 

Psalmus Mortis comes out February 21 on Season of Mist. Pre-order & Pre-save at https://orcd.co/retromorphosispsalmusmortis

“Retromorphosis” upholds the heretical traditions hammered down by the band’s forefather. After all, Spawn of Possession also had a song named after them on their deviant debut. “If you’re going to have a song with the same name as your band, then it has to appear on your first album”, says Jonas Bryssling, who started Retromorphosis during the pandemic after his pick hand was once again bit by death metal’s radioactive songwriting bug.

Put under the microscope and the band’s new single does share SoP’s unreplicable DNA. Christian Muenzner zips through not one, not two, but three guitar solos, each one packed with more technically innovative twists than a triple helix. No matter which way their tales leave you tossing and turning in the dead of night, all of the songs on Psalmus Mortis spiral into madness, but on “Retromorphosis”, Dennis Röndum growls like a man freshly possessed by the devil on his massive shoulders. “I’m the one / chosen son / gifted and reborn“.   

While marked by their beastly signature skills, Psalmus Mortis adds more raw edge to the mix. The album was produced by fellow Swede Magnus Sedenberg, who’s been the band’s preferred death dealer since Spawn of Possession’s first two demos. But Retromorphosis scrapes away all of the studio polish that’s become fashionable even in today’s underground. As shown by his latest bass playthrough, Erlend Casperson can groove along the same brain waves as the most high-minded shredders, but his tone on their new single reeks of the gutter. 

“I prefer my death metal to sound ugly and mean”, Bryssling says with a satisfied grin. 

More muscular face pounding isn’t Retromorphosis only hideous mutation. As Bryssling rips into chunky riffs with the unsavory appetite of an old-school cannibal, ex-Decrepit Birth drummer K.C. Howard beats you senseless with rabid blasts and pounding double bass. But while less techy, Psalmus Mortis does experiment with some unconventional instruments of torture. “All I hear is voice of God / it never leaves me“, Röndum declares in depraved glory, backed by sinister organ glows and a choir of angels who raise their voices as if condemned to the depths of hell. 

“We had rules in Spawn of Possession”, Bryssling explains when asked what separates Retromorphosis from his earlier offspring. “Everything had to always be so intense. Retromorphosis is more free. Psalmus Mortis can be eerie, doomy or even quite simple”.

While a fresh mutation, Retromorphosis are a proven batch of tech-death freaks. The band contains former members of Spawn of Possession, Obscura, Necrophagist and Decrepit Birth.

Each of their singular talents is a legend in their own right, but the raw spirit of Retromorphosis’ upcoming debut album Psalmus Mortis springs from the ghoulish grooves of bassist Erlend Caspersen. Along with SoP’s revered Incurso, Caspersen has played with IGORRR, Blood Red Throne and Deeds of Flesh.  

Today, Retromorphosis are releasing a new bass playthrough of the band’s latest single. Caspersen’s fast and filthy bass runs are the gnarled roots from which the twisted tale of “The Tree” takes its almighty hold.

Even among the accursed crypts of death metal, true legends never stay buried.

Back in 2017, Spawn of Possession were lowered into the grave, leaving behind a swarm of influence. Many fellow demons have followed in their inexplicable wake. But after festering underground for much of the past decade, just last year, SoP respawned as Retromorphosis. In the process, they’ve unlocked the missing link in tech-death’s evolutionary chain.   

Today, Retromorphosis are ringing in 2025 with the second single off their upcoming debut album Psalmus Mortis. On “The Tree”, this new band of proven killers turn an age-old tale into fresh cosmic horror thanks to some old-school tricks of the trade.

Last year, Jonas Bryssling and his old Spawn of Possession bandmates returned from the shadows on their screamer of a lead single “Vanished”. But Retromorphosis are no apparition. True to its name, the second single from Psalmus Mortis towers above the field.

“The Tree” springs to life with the familiar crunch of Bryssling’s filthy riffs. But the song quickly branches out into freshly rotted rhythmic offshoots. New transplant KC Howard (ex Decrepit Birth) shakes his drum kit with the shattering force of an earthquake. “I prefer my death metal to sound ugly and mean”, Bryssling says with a satisfied grin.

For Psalmus Mortis, Retromorphosis reunited with fellow Swede Magnus Sedenberg, who’s been their preferred engineer of death since Spawn of Possession’s first two demos. But for their new album, they opted for more of the raw production that defined the scene during the early ’90s. Though knotted with mind-bending leads and a splintering, white-hot solo that’ll make you wonder if the band’s dueling axemen have grown an extra ten fingers, “The Tree” is cold and unmoving thanks to Erlend Caspersen’s bludgeoning bass grooves.  

“There was no hesitation”, Bryssling says about respawning with his old bandmates as Retromorphosis. “I don’t have to tell them much. They know how it’s done”. 

While less techy, Retromorphosis still delight in concocting freakish experiments. Just below the topsoil of the mix, a glowing bed of organ shrouds “The Tree” in an alien chill. “That’s something old-school bands had”, Bryssling says about the song’s foreboding atmosphere. “I really like that. The organ is my favorite instrument. I just kept adding it to every song”.

All of the tales within Psalmus Mortis are grim, but “The Tree” stems from a truly evil fantasy. “There’s a theory that all human consciousness is connected like the nodes on a tree”, Bryssling says. “This song is about a greedy man who tries to harvest that tree, only to ruin it”. Everyone’s heard the story of the Garden of Eden, but Retromorphosis have no mercy when it comes to enforcing eternal punishment. It ends with a sinister twist, but fans won’t be surprised to learn that things turn out badly for the song’s anti-hero. “Everything around him was dead“, our gruesome narrator Dennis Röndum growls with maniacal laughter.     

“We had rules in Spawn of Possession”, Bryssling explains when asked what separates Retromorphosis from his earlier offspring. “Everything had to always be so intense. Retromorphosis is more free. Psalmus Mortis can be eerie, doomy or even quite simple”.

Even a lawless field like death metal has exceptions that prove the rule. Retromorphosis spawned from a unique leader of the genre, but their unholy union on Psalmus Mortis is a living testament that you can’t bury what was already undead. 

Spawn of Possession remains one of modern metal’s most accursed influencers. During the early to mid-2000s, the noctambulant Swedes toured both sides of the Atlantic alongside Cannibal Corpse and Hypocrisy. Having scaled the accursed summit to reach death metal nirvana on what was only their third album, after three decades, the band was put to rest. But like an especially pungent spore, the seeds of SoP have been festering in its hallowed crypt, waiting to come alive and haunt the earth once more.  

Such is the sordid backstory of Retromorphosis and their debut Psalmus Mortis. In 2020, amidst the pandemic’s endless lull, one of Spawn of Possession’s founding members was again bitten by death metal’s radioactive songwriting bug. “I wanted to make an album that wasn’t tied to anything we’d done before”, says Jonas Bryssling. While this new batch of malevolent creations still stemmed from his punishingly technical fretwork, the riffs were splitting off into even more twisted headbanging directions. But to bring these relentless mutations to life, first, he needed a familiar spark.   

“There was no hesitation”, Bryssling says when asked about resurrecting the creative energies with his former Spawn of Possession bandmates. Pairing back up with rock-solid vocalist Dennis Röndum and elastic bassist Erlend Casperson once again yielded promising results during the early phases of Psalmus Mortis. To further test the equation, they added another familiar but no less fearsome shredder. Before joining them for Incurso, Christian Muenzner lent his flaming left hand to two other stone-cold classics: Necrophagist’s Epitath and Cosmogenesis by Obscura. “I don’t have to tell them much”, Bryssling continues. “They know how it’s done”. 

Indeed, time has only fermented this group’s mutant chemistry. After spending the summer of 2023 recording Psalmus Mortis in their underground laboratory, Retromorphosis emerged with the missing link in technical death metal’s evolutionary chain. “Vanished” officially cracks open its beaker with the satisfying crunch of the old school, steamrolling out a rugged red carpet for Röndum’s imposing growl. It was the first song Bryssling wrote during the album’s initial trial period, but the band continued to tinker with the album’s eventual lead single after the other eight tracks were hammered into gruesome shape. Muenzner’s solos scream like a poor unsuspecting soul who’s being dragged into the shadows. All the while, Casperson flogs his bass as if hiding a mischievous grin, its ghoulish bounce bringing the lyrics’ cosmic body horror into frightening focus.  

“We had rules in Spawn of Possession”, Bryssling explains, as a matter of fact. “Everything always had to be so intense. Psalmus Mortis is intense, too, but it can also be eerie or even quite simple”.  

Simplicity might not be Retromorphosis’ dominant chromosome. Even though it’s fueled by straight-forward, down-picked chugging, the album’s nine-minute monolith “Machine” churns through multiple tempo changes, cranking up the tension with every accelerated blast beat. But the band did opt for a leaner chemical base. Psalmus Mortis was produced by Magnus Sedenberg, who’s been the band’s Swedish engineer du jour dating back to Spawn of Possession’s first two demos. “Reuniting with Magnus felt like the natural thing to do”, says Bryssling, “but for this album, we scraped away some of the studio polish”. With its sludgy distortion and hallucinating speed, “Never to Awake” certainly summons the ’90s untamed spirit. “I prefer my death metal to sound ugly and mean”.

While roughly a decade in the making, Retromorphosis still grip it and rip it on Psalmus Mortis. Heck, chunks of the band’s first album were hung up to dry like butchered livestock after just one crack in the studio, much to their own amusement. “I don’t think there’s a single first take on the SoP albums”, Bryssling laughs. Röndum doesn’t mince words, either. He chews through syllables with all the careful consideration of a meat grinder. And while each tale descends into its own sweaty night terror, they all escalate from bad to worse. Despite its seemingly pedestrian title, “Aunt Christie’s Will” unpacks a maze-like mystery that ends with an especially morbid twist.

Of course, given this crew’s technical chops, Retromorphosis were bound to birth more head-spinning experiments. Psalmus Mortis injects fresh blood into their chilling cosmic horrors by fleshing out their technical arsenal with some unusual instruments of torture. The album opens with doomed power chords, pounding drum fills, then…spooky organ glows, tense strings and a ghostly gothic choir. “That was a new experience”, Bryssling says about adding more synthetic textures to the mix, though his inspiration came from a life-long obsession. “That sense of atmosphere was something old-school bands used to have”. The special effects aren’t just saved for its ominous opening instrumental oeuvre, either. “The Tree” puts a dystopian twist on the age-old tale of human greed with synths that glow like alien guts. 

Freakier ambience isn’t the only new life form on Psalmus Mortis. “Everyone knows KC Howard is an insane talent”, Bryssling says. Howard left his brutally precise mark on the scene when he was behind the kit for Decrepit Birth, though Retromorphosis were formally introduced to their new drummer through Röndum, as the two had crossed paths during an episode of the Cali Death Podcast. Howard’s nuclear barrage of double bass kicks feeds the band’s cellular engine like jet fuel, driving high-flying album closer “Exalted Splendour” toward its blinding conclusion.  

Ask Bryssling to identify what separates this new baby from their first born and the answer is, in fact, quite simple.”Retromorphosis is more free”. Put the song that bears their name under the microscope and feast your eyes on everything this band are capable of: non-stop blasting, brain-bursting bass fills, solos that would fry a supercomputer and pure unholiness. “I’m the one / chosen son / gifted and reborn”.  

With Psalmus Mortis, technical death metal’s chosen ones rise from the grave.
