Astriferous slimed out of the Costa Rican death metal scene back in 2019 and have been on a slow, upward crawl since. Their 2023 Pulsations from the Black Orb debut grabbed them some attention and a mostly positive review from our own Ferox. Their weapon of choice is repugnant caverncore with a dose of dissonance, putting them squarely in the Incantation, Dead Congregation, and early days Tomb Mold wing of the death emporium. Atavistic Unraveling finds them stuck in the same filth and scum with scant migration toward the light of day. It’s still fugly, grotesque death metal of the olden school, with the dissonance element adding a slight touch of modernity. Their sound is a bit more fleshed out this time, and when everything clicks, things can feel pretty goddamn harrowing and brutal. With so many bands trying to ape the classic Incantation sound and vibe, can Astriferous do enough to crack through that thick mucous membrane and claim their share of the cesspool? Let’s test the tainted waters for hazardous algae.
Fucknormous opener “Carriers of the Curse” is a fine way to kick things off, and it has all the crucial elements. It’s not doing anything new, but it comes after you with so much raw savagery that innovation starts to seem trivial. It covers all the bases a caverncore tune should, from ragged blasting to slower mid-tempo plodding, and there’s a meatheaded Cannibal Corpse vibe to the riffs when they aren’t being all snakey and creepy. The only downside is that it feels like the song rambles on for about a minute too long, revisiting the same scorched territory. “The Floating Catacombs” is more of the same high-quality ear abuse, with slimy, repulsive riffs and subterranean vocals teamed with caveman moments and some weirdly Voivodian riffs popping in and out for variety. As the album churns along, you get quality nastiness, but there’s that nagging tendency to stretch out compositions a bit too far, reducing the overall impact. This despite the fact that most song run between 4-5 minutes. It’s a weird thing. “Proto Embryo (The Third Tribulation)” is a remorseless blast furnace with just enough tempo shifts to keep things interesting, but it just keeps going when it feels like it should be over. Likewise, “Arcane Demonomania” is another blistering ass blaster with a jagged d-beat and a plethora of ugly, squiriming riffs. It’s easy to love, but once again, it drags on toward the end.
A few tracks are good but less impactful, like “Mnemonic Phenomena,” despite some effective doomy segments and overwhelming vocal excess. 8-plus minute closer “Resonance Cascade” is more modern-sounding, venturing into sludge doom at points. At its best, it can feel oppressive and suffocating. Over the whole runtime, though, it ends up challenging the attention span as segments of less interesting riffs drift by, offering little to cling to. The album’s nearly omnipresent sense of bloat makes a 36-minute album feel much longer than it is, which is a shame because Astriferous do so many things right here.

Felipe Tencio and new slinger Esteban Sancho are at the center of a maelstrom, casting frantic corkscrewing riffs in all directions when not laying down big power chugs that put the boot on the throat. This tandem knows the ways of caverncore, and many of these leads probably slithered away after recording to become invasive species somewhere. Incantation is a clear influence, but I also hear Immolation, Morbid Angel, and Cannibal Corpse in the DNA. Tencio is a great death metal vocalist possessed with a deep, intimidating roar for the ages. He sounds demonic and gigantic and anchors the material to the Ninth Level of Hell. José Pablo Phillips also impresses with a pronounced and weighty bass performance. The only real knock is that the writing can be undisciplined and too long in the fang, thereby partially unraveling the band’s good works.
Astriferous have a winning formula and the talent to execute it, and parts of Atavistic Unraveling scream of potential and hint at greatness. With tighter, more consistent writing, this would be a must-hear and headed for my year-end list. As it stands, I can safely recommend this for death heads everywhere as the wet, sticky goods are delivered, even if they aren’t all equally malicious and infectious. Like my great-granddaddy Pig Iron Druhm used to say, “If the cave smells of rancid mold, there’s bound to be some gold.” Wisdom!
