Having evolved into one of the most innovative curios in the extreme metal kingdom, after three decades, Spawn of Possession was put to rest back in 2017. But as decreed by the laws of death metal, you can't bury what's already undead. Like an especially pungent spore, the seeds of SoP have been festering underground, waiting to come alive and haunt the earth in the form of an even more ghastly mutation. Such is the sordid origin story behind Retromorphosis. After the demise of his first musical baby, guitarist Jonas Bryssling began writing new songs that incorporated more of his own maniacal sensibility into Spawn of Possession's influential DNA. While hatching his formula, Bryssling linked back up with SoP vocalist Dennis Röndum and bassist Erlend Caspersen, along with the shredding Swiss army knife Christian Muenzner (ex-Obscura and Necrophagist), before adding former Decrepit Birth drummer KC Howard to the mix. The results of this experiment will satisfy metalheads who've been searching for the missing link in tech-death's evolutionary chain. Retromorphosis' first full-length is bursting with freakishly fast riffs, warped rhythmic precision and cosmic horror. "Vanished" officially cracks open the chemical beaker with a familiar yet no less bone-shaking growl, while adding heavy droplets of old-school crunch. Psalmus Mortis also finds these most deviant of metal evangelists spreading evil by implanting more seeds of horrific sci-fi. "The Tree" puts a dystopian twist on the age-old time of human greed with a stomach-knotting solo and synths that glow like alien guts. Put the song that bears their name under the microscope and feast your eyes on everything Retromorphosis 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 are reborn.
