Born Of Osiris at The Underworld, London 2026

The stairs down into The Underworld are steep, but on the night of January 18th, I felt like I was descending something even deeper, as a ritual chamber carved just for this kind of music. It’s no secret that Born of Osiris commanding a stage in London is an event, as it was three years ago at this same venue. The fact that the gig had originally been slated for Islington Assembly Hall before being moved to The Underworld only made the urgency buzzing through the crowd.

They may have been the reason many of us were there, but this night was never going to belong to just one band. With Larcɇnia Roɇ, Aversions Crown, and Within Destruction stacked beneath them, the lineup read like a carefully constructed descent into chaos; each act pushed the room further until there was nowhere left to go but straight through the wall.

Larcɇnia Roɇ

Opening a show like this is a brutal task, but Larcɇnia Roɇ treated it like a challenge. As soon as they took the stage, any lingering conversations were swallowed whole by a sound that felt feral and unhinged in the best way. Their debut album Extraction and recent single “Lean” (which they’ve been keen to push on this tour) set a tone of controlled ferocity: jagged, unpredictable, and alive.

They launched into a vicious set that immediately spoke in terms of raw energy rather than polished structure. Frontman Ryan Vail unleashed vocals that scraped the ceiling and rattled the ribcage, while the guitars felt deliberately uncomfortable, and the drums came down like blunt instruments. Despite their early slot, a small pit under the stage formed instantly. Even those who arrived solely for Born of Osiris couldn’t help but be won over by the sheer force of their presence. They left a mark, establishing an aggression and intent that would carry through the rest of the night.

Aversions Crown

When Aversions Crown stepped up, the heat in the room deepened. Brisbane’s own have been described as delving into “progressive alien deathcore”, and seeing them live made that strange descriptor make sense. Singer Alex Teyen stood firm, voice towering with guttural command, while guitarists Chris Cougan and Mick Jeffery carved those signature oppressive riff patterns that feel like swirling currents rather than straightforward blasts. Behind them, Jayden Mason on drums was metronomic and monstrous, threading through tribal rolls and crashing breakdowns with impeccable precision.

The crowd responded in a more restrained way. The pit during their set was nearly nonexistent; movement was minimal, with people standing their ground, absorbing the weight of each breakdown rather than acting on it. The room felt unified not through motion, but through collective attention, as if everyone was bracing internally for every crushing impact, especially during older bangers like “Hollow Planet” and “Erebus”. In that sense, Aversions Crown’s performance didn’t rely on theatrics or banter, but it spoke entirely through sheer sonic weight.

Within Destruction

If Aversions Crown dragged us into the void, the Slovenian guys from Within Destruction kicked the door off its hinges and demanded movement. They brought a guttural and precisely calibrated onslaught, blending deathcore brutality with technical sharpness and flashes of metalcore and nu-metal influence. It was like flipping a switch, with everything going sharper, faster, and heavier. Tracks like “ANIMETAL”, “No Way Out”, and “CYBERGIRL” hit with the kind of brutality that sends reverberations through every inch of your body.

Rok Rupnik prowled the stage with an insatiable intensity, his vocals snapping between guttural lows and frantic screams. Guitarist Howard Fang drilled razor-sharp riffs into the mix, while Luka Vezzosi’s drum assaults were both relentless and meticulously placed. The Underworld’s famed sound system only magnified the onslaught, and for many of us, it was impossible not to feel the visceral thrill of watching such intense musicianship played with synchronicity and intent.

This was the point of no return for the crowd. The pit finally exploded, and because this room doesn’t give you space, that explosion was all in your face. Every heavy breakdown catalyzed animalistic response; I saw people pulled up from the floor only to throw themselves right back in, grinning like maniacs. When Within Destruction left the stage, the crowd was exhausted but visibly exhilarated, having pushed the room to its physical limits.

Born of Osiris

By the time Born of Osiris took to the stage, you could almost taste the anticipation. The lights dimmed, the intro swelled, and then it happened: that unmistakable blend of technical mastery and emotional weight crashing down all at once. There was no reverence left to build; everyone was already tuned in.

Vocalist Ronnie Canizaro was in formidable form, shifting effortlessly between guttural brutality and soaring melodic lines. Cameron Losch, the band’s rhythmic backbone and sole remaining founding member, was a commanding presence; every hit felt intentional, every fill perfectly placed. Watching him play in such close quarters was a privilege. Nick Rossi’s guitars and synth layers, hallmarks of Born of Osiris’ sound, filled the venue, wrapping around the crowd like a living thing.

Songs from across their catalogue hit hard, old and new blending seamlessly into a set that felt both nostalgic and forward-looking. When the familiar riffs of “Bow Down”, “Follow the Signs”, and “Under the Gun” kicked in, the reaction was immediate: fists in the air, lyrics screamed back with raw emotion. In these moments, the band’s perfect blend of progressive metalcore, technical deathcore, and immersive synth textures washed over the crowd like an emotional tsunami.

But when they played tracks from their latest album, Through Shadows, it was surprising to hear how they hit even harder on that stage. “Elevate” was a blend of layered synth textures and galloping riffs, creating a beautiful tension that beckoned movement across the floor. “In Desolation” was equal parts cinematic tension and jagged metal precision, while “Through Shadows” pulled the emotional focus even deeper. The crowd’s reaction to these songs told you everything: people weren’t just listening; they were living in each beat.

There were smiles exchanged, fists pumped without restraint, and that pure, unspoken brotherhood that only comes when hundreds of strangers have chosen to feel the same thing at the same moment. And when the set reached its conclusion, the encore felt like a release valve finally opening. The pit erupted one last time for “Machine”, the floor vibrated like it might give way, and every single person was totally immersed in the moment.

From Larcɇnia Roɇ’s raw energy, through Aversions Crown’s oppressive tension, Within Destruction’s kinetic brutality, to Born of Osiris’ emotional and technical mastery, every act brought a distinct voice to the night’s narrative. As people drifted out into Camden, replaying breakdowns in animated fragments of conversation, The Underworld still seemed to hum with the aftershock.

That’s the magic of nights like this: the music feels loud in your bones, in your chest, in your memory long after the echo fades. It’s a tribal gathering of souls who speak through distortion, rhythm, and raw emotion. And for a few hours underground, we were all part of something larger, louder, and beautifully chaotic.
