The Chilean thrashmongers in Critical Defiance have been slinging molten riffs and high-octane violence for over a decade, and on fourth LP Rivers of Blood the carnage continues. The band formed in 2010, and though they released a couple of demos and a split between 2014 and 2016, it took nine years before the world got its clutches on full-length debut Misconception. Since then, Critical Defiance has maintained a steady release schedule with sole original member Felipe Alvarado at its epicenter. In his review of Misconception, the esteemed Cherd observed that while Critical Defiance nailed the construction of riffs, weaving them into a coherent whole fell short. Seven years and three albums later, does Critical Defiance drown out the detractions in Rivers of Blood?

Rivers of Blood feels and sounds like the culmination of everything Critical Defiance has accomplished so far. Where Misconception put the world on notice with whirlwind riffs weighed down by a touch of bloat, sophomore record No Life Forms trimmed the fat and honed Critical Defiance’s thrash attack to a keen knife’s edge. Follow-up The Search Won’t Fall… ballooned the runtime back out,¹ seeing a wide range of track lengths and engaging compositions that, while good, dealt less urgency than its predecessor. Like No Life Forms, Rivers of Blood reins in the runtime to a scant half hour while lacerating listeners with razor-sharp riffs, supplying an electrifying swing back into the less-is-MOAR camp. The immediacy of Rivers runs rampant across thirty-one minutes, where Critical Defiance rips and rages across tracks like “Innate to Kill” and “Glorify War” without ever feeling rushed. Conjuring the likes of Kreator, Sadus, and Exumer on Rivers of Blood, Critical Defiance continues their aggrieved assault without compunction.

Alvarado floods Critical Defiance with a talented cast, and nary a dull moment dams the Rivers of Blood. Though featured in previous albums, the acoustic passages on opener “Red Omen” and interlude “Ceremony of the Final Call” imbue Rivers of Blood with wistful moments that offset the murderousness heard elsewhere. Album centerpiece “Valparaíso” also features captivating acoustic strums, but that’s not all—Alvarado channels the spirit of Kreator’s Mille Petrozza on vocals, bassist Diego Tello discharges truculent low-end thunder, drummer Rodrigo Poblete detonates dynamite fills with frenzied velocity, and guitarists Mauricio Toledo and Sebastián Palominos (along with Alvarado) create intricate layers of leads and riffs that guide listeners through the track’s eight minutes. As good as “Valparaíso” is, though, other tracks consistently bolster Rivers of Blood’s savage competence. “Innate to Kill” pushes Critical Defiance’s speed full throttle while “Rivers of Blood” eases the relentless ferocity to highlight clean backing vocals and a pugnacious strut. Additionally, “Glorify War” proves a strong closer. The bass intro barrels into full-blown chaos, and, by the end, Critical Defiance’s wicked barbarity meshes with acoustic frills to end the album by uniting the delicate with the domineering.²

With all the positive momentum condensed into such a tight package, Critical Defiance leaves little room for complaint. The production lends a throwback aesthetic that might seem muddy, yet every instrument cuts through the mix without feeling overcrowded. The songwriting demonstrates clever tension and pacing, where frenzied riffs circulate in swelling storms as songs surge into seductive solos (“Valparaíso”), churning chugs (“The Feeling Destroyer”), and the aforementioned acoustic threads (“Rivers of Blood,” “Glorify War”) that tie the entire album together. Conversely, my quibbles are minor, like wishing for a little more cohesion during the transitions on the back half of “Valparaíso” or a bit more riff development on “The Feeling Destroyer” and “Dead Tongues.” Not that the licks are drab by any means, but Critical Defiance seethes with expertise, and their flashes of technicality characterize the best moments on Rivers of Blood.

Critical Defiance unleashes torrents of riffs and vitriol on Rivers of Blood, imperiling the levees of restraint with its most potent moments. On album number four, these Chileans prove that their arrangements flay with finely-tuned precision and evoke the old school without ever feeling stale. What I enjoy most about Rivers of Blood is the act’s balance—retro and fresh, gentle and primitive, straightforward and complex. Rivers of Blood teems with vitality and a head-rattling punch, and Critical Defiance’s chops and maturation continue to progress and impress to an extent that I eagerly anticipate what they do next. Until then—stay Bloodthirsty my friends.
