Enter Sedimentum. Suppuration morphogénésiaque was at the top of my year-end list that year, and it was their phenomenal use of cavernous, depths of the molten earth production alá Incantation and Writhing. As of this writing, they have released two Demos and two splits and hopefully, there will be a new full-length following this mini album.

But we’re in the here and now and anything is good when these guys are involved so it was no surprise that I was beyond excited when I saw that they were releasing a new anything.

I’m not disappointed either; Derri​è​re les portes d’une arcane transcendante is a fucking infernal beast clocking in at a respectable 21:02 and Sedimentum bring their cavernous, Incantation style Death Metal to the slimy core of the earth to once again bludgeon the ears of the unsuspecting masses.

“Vilénie” gets it going right away with some eerie intro vibes that rise and fall like rogue waves before the music grabs you and throttles you with fists of enraged fury. For 7:01 minutes you’re taken on a roller-coaster ride. It’s a slow roller-coaster ride though, this is where Sedimentum shines; a slow death underneath a pile of rocks, a totally crushing delivery.

“Le labyrinthe sempiternel” is the second salvo from Sedimentum’s arsenal, and it’s absolutely deadly. Explosive blasting and that murky atmosphere of dread that permeate through the three tracks. It’s completely menacing how they switch from striding blasts into a rolling thunder double bass monstrosity.

The closing track “Inhumation céleste (Au carillon mordoré)” hits you in the in the chest like a shotgun blast. Incoming riffs act like rusty razors to flay the eardrum and bore deeper into the center of the brain. There’s a killer breakdown near the beginning of the song that’s seismic, and Sedimentum keeps changing tempos with the deftness of a Fencing master. It’s a 7:30-minute giant and brings the best conclusion possible.

If you love the groovy sounds of Incantation, and the mighty Writhing, Molder or Maul; or just cavernous Death Metal that drags you through a decaying swamp of riffs and earthshaking rhythms, then Derri​è​re les portes d’une arcane transcendante is the album for you. Get it right away.

Hailing from Quebec, and active since 2018, the four-piece released two demos and two split albums before spawning Suppuration Morphogenesiaque. Sedimentum plays with a cavernous production, guitars, and bass churn in the stygian miasma, creating an Incantation-influenced sound; murky and sinister. I must make the comparison to Incantation; this is not a bad thing I promise you, because it is the sound that Onward to Golgotha and Mortal Throne of Nazarene made famous.

This isn’t just a blast-laden slab of Death Metal, as track two “Excrétions Basaltiques” demonstrates with a slow, churning atmosphere. Sedimentum knows how to pace an album with the title track bouncing between gut-churning slowness and brutal savagery. I could even make a comparison to Last Days of Humanity and Blasphemy and not be worried about repercussions. This is bear attack brutality.

“Nécromasse”, “Supplice” and “Un Grotesque Panorama” fill out the remainder of the album with “Supplice” being an anti-Christian burner and “Un Grotesque Panorama” being the end sludge that comes from industrial waste depositories. In the end, I have listened to this release constantly, as far as debut albums go this is a fucking killer and I cannot recommend it enough. Show these guys some love and you won’t be disappointed.
