Born of Osiris – Heavy, Technical, Chaotic in the best of ways

Prog metal, Chicago born five piece Born of Osiris took over the historic The Underworld in Camden on January 18th, following a very last minute venue change from The Islington Assembly Hall.

With some of the best and weirdest deathcore and metalcore modern bands in tow, this was one of the most serious lineups the storied venue has seen in a long time.

Larcenia Roe kicked off the night with their very unique, horror approach to deathcore, a stop/start cadence that leaves you constantly wondering what the hell comes next. Following their release of the very well received Extractions back in May 2025, the band has now established itself as one to definitely watch.

The combination of horror masks, the pig squeals and a seriously impressive portfolio of weird vocal choices from Ryan Vail lets the band sacrifice pure heaviness and brutality in favour of a more stylistic approach to deathcore. It’s definitely on the fresher side of things for a genre that’s usually just about raw emotion.

Australian self proclaimed “progressive alien deathcore” Aversions Crown came next, with a blend of insanely technical compositions and weird lyrics about alien invasions and sci fi themes. This is a very technical band, not afraid to throw the typical breakdown to the side in favour of more riffs, clear mixing and transitions.

Main support sees Slovenian Within Destruction bounce on stage, accompanied by a huge wash of neon lights, a theme they kept close since the change to a more Japanese inspired, metalcore heavy sound with the releases of Animetal, Lotus and Yōkai.

For what started as a fairly traditional deathcore band back in 2010, their new sound and the member changes have been very well received by the deathcore and metalcore community, even if there still are the supposed OG fans out there that would prefer if they would switch back to a more brutal, breakdown heavy style.

For The Underworld crowd, none of this seemed to matter. Circle pits quickly formed around the pillars on the floor, lyrics were sang back to the band, and the heat in the room went up by a few degrees with the sheer force and adrenaline they unleashed on the tiny stage.

By the time Born of Osiris came out, the 300 cap venue was hot, sweaty, and packed elbow to elbow.

The crowd erupts into a roar as vocalist Ronnie Canizaro and sole remaining founding member Cameron Losch take the stage, the latter sitting triumphantly on a drum kit thrown at the back of the small stage, where he’ll be commanding the room for the next hour and a half.

After more than twenty years of tearing through towns and rhythms, Born of Osiris quickly show that they too, are a different breed compared to classical metalcore or deathcore. Polyrhythmic fills played with a wide grin by Nick Rossi, a technically complex show of rage behind the kit being drummed out by Losch, and a mix of clear scream and gutturals from Canizaro made them look like they were headlining a stadium not a small room hidden well underneath the Camden High Street.

The setlist was well balanced between the newly realeased Through Shadows and older works from The Discovery, even going as far back as 2007 with Abstract Art, Bow Down and Empires Erased from The New Reign.

It was a vibrant one, sound and bodies bouncing off the walls of an almost capped venue on a late Sunday night in January.

Don’t sleep on any of these bands, they are truly special. Setlist for Born of Osiris below, can’t wait to see them next, on a well deserved biggest stage!
