Bury Tomorrow have secured their status as one of the UK’s most energetic, engaging and prolific metalcore bands over the past couple of decades. Tonight they headline the O2 Victoria Warehouse able to bring their show to the biggest stage yet. The whole bill is packed with talent from across the globe, and a variety of takes on metalcore, with sets from Siamese, Lionheart and Nevertel.

The venue’s far from packed as Danish genre-mixers Siamese take the stage, and up in VIP it’s practically deserted. But they ensure that every last person in the crowd is bouncing and blown away with their expansive big stage performance. The set opens with Christian Hjort Lauritzen stood as a solitary figure under a spotlight - violin in hand, atmospheric backing track swirling around him. It’s a haunting intro that quickly gives way to a full-band eruption bathed in red light. The energy kicks up instantly with up-tempo rhythms, danceable tracked synths, and a slick sense of showmanship. They dive into ‘Chemistry’, and it’s a reminder of what makes Siamese so compelling - those soaring vocals from Mirza Radonjica paired with beefy, distorted guitars that snarl with intent.

They joke about having played Rebellion a million times, clearly relishing the chance to stretch out on a bigger stage tonight. ‘Down’, a new and still-unreleased track, hits hard from the outset with stabbing guitars and a vocal performance that’s nothing short of a showcase. Mirza’s cleans are glorious, his harsh vocals vicious - both have evolved dramatically in recent years. Stylistically, Siamese have now diverged from their Danish peers like VOLA and A Cold Night for Alligators, instead aligning more with French melodic heavyweights Resolve, Landmvrks, and Novelists. They close with ‘Ocean Bed’, complete with a lush violin reprise and guest vocals from Bury Tomorrow’s Tom Prendergast. It’s a superb finish - elegant, emotive, and powerful.

Next up are Northern California’s Lionheart, who waste no time unleashing chaos. A thrashy, sample-laced intro and strobing spotlights set the tone before they charge onstage and deliver pure hardcore fury. It’s two guitars and no bass tonight – with bassist Richard Mathews filling in on vocals due to singer Rob Watson’s absence due to personal reasons. The result is the same though – charismatic, raw, West Coast hardcore through and through. There’s gang chants, beatdowns, and a sound that channels Pennywise, Deez Nuts, and Stick To Your Guns. It’s a gritty, genre-splicing set that hits hard with the hardcore end of metalcore awesomely showcased by a truly professional and engaging band.

Main support tonight comes from Florida act Nevertel, and things take a turn. With guitar, drums, and two vocalists, they land somewhere between Hands Like Houses and a boyband with a touch of high-pitched rapping. It’s an odd mix – with the cleans very whiny vocals, an undefined guitar tones, and a lack of hooks. The first track is definitely a hard pass. The second edges closer to Normandie territory and even flirts with Siamese’s style, but it’s still not quite there.

By the third song, they’re clearly aiming for Linkin Park vibes and it’s at these points that their strongest moments are revealed – Jeremy Michael in Chester Bennington mode and Raul Lopez channelling Mike Shinoda. But there’s a distinct lack of identity going on here and I’m not sure that what they’re trying to achieve is meant for this kind of bill. It’s a bit too close to their influences as well. Lopez grabbing a guitar just to strum on the chorus feels too Mike Shinoda, too tribute act. There’s potential with these guys, but currently it’s buried under homage.

Finally, the lights dim and the venue roars for tonight’s headliners, Bury Tomorrow. They stride out to a reworked ‘The Purge’ announcement, sirens blaring, and launch straight into ‘Choke’. It’s a perfect example of their catchy metalcore that has a signature, distinct style of its own. The staging is full arena mode - drums on one riser, bass dead centre, and keys on another riser to the side allowing Tom Prendergast freedom to roam and lead the clean vocals when the moment calls. Frontman Dani Winter-Bates stalks the front riser like a caged animal, and the energy is electric. Tom’s cleans are sublime, soaring without fail, and Dani is as raucous and impassioned as ever. The guitar work always leaps out live with its intricacy - more layered and impressive than memory serves from recordings.

Midway through ‘Cannibal’ the set halts for a fan in distress near the front, but once she’s safely out, they restart the track, and it’s even more powerful the second time around. Finger-tapped guitar lines shimmer subtly beneath the verses, adding depth without distraction. It’s this kind of detail, combined with massive hooks and choruses, that elevates Bury Tomorrow above their peers. Both guitarists trade off tapping and riffing with wild abandon, and the chunky grooves hit hard every time on every track. Dani delivers a fiery speech about corporate greed and right-wing politics, but the mood quickly shifts to unity and supporting each other. Siamese are dancing full throttle behind me, arms raised, and the whole room feels just as alive. It’s a triumphant, cathartic end to a night that builds every moment fully to a full-throttle communion.
