Deathcore is a genre that’s constantly threatening to eat itself alive. For every band trying to push boundaries, there are ten more content to recycle the same breakdowns, the same vocal gymnastics, the same studio-polished violence. Osiah, however, have never been interested in playing it safe and their latest EP Aion is proof that they’re still operating on a level most of their peers can’t touch.
Clocking in as a short but merciless offering, Aion feels less like a stopgap release and more like a concentrated dose of everything Osiah does best. This is deathcore stripped of novelty gimmicks and rebuilt as something genuinely oppressive. The breakdowns hit with familiar weight, sure, but it’s the way Osiah manipulates tension that makes this EP feel different. Guitars are tuned so low they feel less like instruments and more like environmental hazards. Riffs don’t just chug but lurch, stall, and collapse in on themselves, creating a sense of unease rather than predictable payoff.
Vocally, Ricky Lee Roper remains one of the band’s most dangerous weapons. His performance across Aion is less about range for range’s sake and more about command. High-pitched screams slice through the mix with surgical precision, while the gutturals sound downright anatomical. They feel like they’re tearing the song open from the inside. It’s not flashy. It’s authoritative. The vocals don’t sit on top of the music but feel embedded in it adding another percussive element designed to suffocate.
What really elevates Aion is Osiah’s refusal to let momentum flatten into monotony. Tempo shifts arrive without warning, riffs mutate mid-phrase, and breakdowns often dissolve before they fully resolve. There’s a constant sense that the band is pulling the floor out from under the listener. This unpredictability keeps the EP engaging even when the sonic palette is undeniably brutal. It’s heavy, yes, but it’s also restless. Fans of Born Of Osiris and Thy Art Is Murder will love this.
Longtime listeners will recognize threads from earlier releases like Kingdom of Lies and Loss, particularly in the band’s balance between technical precision and emotional weight. Since signing to Unique Leader Records, Osiah have steadily refined their sound without sanding off its ugliness. This EP continues that trajectory, but with a sharper focus. Where Kairos sprawled and explored, this EP tightens the vice. Every moment feels intentional, every second designed to maximize discomfort.
With that said, Aion isn’t trying to reinvent deathcore and it doesn’t need to. Its strength lies in execution. Osiah take familiar tools and wield them with a level of conviction that many bands lack. There’s no sense of trend-chasing here, no wink at the audience. This is a band that sounds fully committed to making the listener feel trapped inside the music.
In the end, Aion functions like a blunt-force reminder that deathcore can still be terrifying when it’s written with purpose. Osiah don’t just pile on heaviness but weaponize it. If this EP is any indication, they’re not interested in easing up anytime soon, and honestly, that’s exactly how it should be.
