Review: “Fever Dreams of Vengeance” by Sewer Altar

In the summer of 2024 while everyone was going to festivals, drinking beers and shouting obscenities at the government, Finnish death-grind provocateurs Sewer Altar  released a ten minute six track demo. Running on traditional Death Metal themes of defilement and horror, intertwining them with the pervasive malaise of sociopolitical inequality, thriving on short, sharp bursts of intense aggression in sonic abrasion, it gained plenty of interest. Taking things one step further the band have now completed work on a debut album in “Fever Dreams of Vengeance” which has got no less than four labels in 783Label, Hecatombe Records, 7Degrees Records and Iron Corpse Productions offering cassette, compact disc and vinyl editions. So what have drummer Sakari “R. Charon” Forsman (Hoc est Bellum, Karhunvartijan Tyhjiö), vocalist and guitarist Kalle “Deströyer 161” Leprosy (Below The Gates) and bassist and lead vocalist Ville-Aleksi “Vermis Animus” Valli cooked up this time?

Frantic and frenetic from the very outset “Landfill Sky Burial” slaps you across the face like “Calculating Infinity” era The Dillinger Escape Plan on steroids. Forget Mathcore, this is Grinding Death Metal delivered at breakneck speed that feels like the kind of white knuckle roller coaster ride Devin Swank lives for. The sonic equivalent of a violently shaken box full of sharp objects, its as potent an opening cut as anyone could have wished for with the adrenaline rush of a blink and you’ll miss it moment. What makes it something different is that there is so much going on that you’re going to need to listen to it a hundred thousand times to work it all out as so much pops out of the mix with each repeated listen. By comparison “Tachanka Drive-by” feels like a Death Metal band playing a Hardcore cover, delivering all the heavier elements you’d expect to make it absolutely crush. Blast beats, bass grooves and a lethal guitar tone are all present and correct.

Almost but not quite the bands eponymous song “Altar in the Sewers” is one that reared its ugly head on the aforementioned demo and here is just as venomously vicious. A high octane burst of adrenaline with thunderous percussion that is nothing short of restless and relentless, this one almost feels like it was recorded live on the floor of the studio in a lets see who can play the fastest do or dare moment. There is a down tempo shift before the end, not to mention a fleeting solo which both work incredibly well on this violent delight. Sixty three seconds is all that Sewer Alter need to get through “Fencewalkin Cheetah” as the band deliver the kind of heavy hitting abrasions that the likes of Brad Boatright and Taylor Young usually have their finger prints all over in the studio. It has to be said that resistance is futile when it comes to this album because each track is just so much fun. Annihilation protocol has been engaged by the time “18 and Death” comes out swinging, the groove laden riffage after the initial blast beat assault a moment of mastery.

In two and a half minutes “Deadw8” manages to cross Metal sub-genres with death defying leaps, a blistering Blackened Hardcore Punk section in the middle reaching almost feral levels of insanity before the brutal finale. Here’s the thing though. The introduction is so far removed from what came on the earlier tracks that you might thing you’ve been zapped into another record and that’s part of the charm of this. Its what the edge of the seat was made for! “Cryonaut Sludge” then goes arty with a distorted sample introduction before returning to the trademark skull battering, Valli sounding like an apex predator. His throat splitting vocals are a quintessential part of the Sewer Alter sound but how he manages to play bass at the same time is a mystery.

Taking a leaf from the 90’s American Death Metal sound “Resilient Like a Disease” is another beast of a track, the sinister leads sheer class before “Outnumbered” smashes the clock in fear. If anyone was going to wear a Dying Fetus t-shirt to a job interview it would be Sewer Altar, who deliver a beating with a baseball bat on this prime slab of barbed rhythms. They know only one speed and that’s the tempo of the damned but they do it so well that no-one gives a f***. “Slave Driver Smile” sounds like it was inspired “Punishment” era Biohazard, the hard hitting breakdown laden grooves a headbangers delight. Recorded with an emphasis on raw power and clarity, the incendiary energy flowing through the veins of these tracks is second to none. Once more with feeling they bring out the dead with “Writing on the Wall“, a track upon which the buzz-saw guitars and galloping drums ensure tinnitus for anyone who would dare listen [8/10]
