On October 25th, 2025, Gunma Sunburst hosts a joint showcase of brutality: Takasaki Extreme 3 collides with 乱舞 (Ranbu) Vol.7, fusing chaos from across Japan’s hardcore, grind, and extreme punk scenes. The result is a floor-stomping, throat-shredding, absolutely unhinged gathering in the heart of Gunma — all happening inside one of Japan’s loudest steel-box venues.
Lineup
brag-Flashlamp
Takasaki’s own grindcore veterans, brag‑Flashlamp blow open the stage with raw, blasting intensity. Their history in Gunma’s extreme circuit gives them enough grit to pulverize a venue like Sunburst. Think full throttle grind riffing, relentless tempo shifts, and unsettling noise interludes. Their 2020 album 雲外蒼天 and local scene ties make them a backbone act for the region’s brutal lineups.
Final Exit
Tokyo’s Final Exit sits at the collision of grind and absurdity. They lean on blistering speed, chaotic arrangements, and a dark sense of humor. Their sets feel less like songs and more like sonic acts of catharsis — brutal riffs, feedback storms, and riffs that flicker just enough to keep you unsettled. They’re not here to comfort; they’re here to fight.
Little Bastards
Little Bastards bring grindcore urgency wrapped in punk’s rawness. Their attack is compact and ferocious — short songs, no filler, full aggression. Live they’re kinetic, spitting riffs and wrecking the floor with a fury that leaves no time to rest. Expect violence, speed, and a relentless push.
DE-Cultures
Hard to pin. From the placement in the flyer you can feel them leaning toward noise‑punk or experimental hardcore. Their role is to bridge extremes — sometimes static noise, sometimes blast attack — whatever it takes to break the tension. They exist to unsettle and provoke, to hold space between clarity and collapse.
怒号 (Dogo)
Dogo delivers black metal’s bleakness, tuned to underground resonance. Shrill tremolos and chilling dissonance define their aesthetic, with a raw edge that refuses polish. They thrive in darkness: minimal yet vicious, a blast‑straight assault meant for those who want to be haunted by performance itself.
Gut Explosion
Pornogrind as pure as it gets. Gut Explosion’s set is a grotesque carnival of guttural vocals, broken riff skid marks, and beat patterns that feel like they came from some twisted rhythm machine. Offensive by design, heavy by nature. Their presence is an assault; their intent is stomping everything in the path.
Caassimolar
Tokyo’s Caassimolar is a death metal force formed in 2018. Their 2018 demo laid the groundwork and their more recent live album Infernal Region captures their growth, blending crushing riffwork with brutal precision. They don’t sugarcoat — this is grind-tinged, tight, and unrelenting death crafted to collapse the walls.
Venue - Sun Burst
Gunma Sunburst, in Takasaki City, stands as a core pillar of the regional heavy music circuit—an industrial live house built for volume and intensity. It’s a concrete‑walled bunker of sound where stages are tight, speakers are unforgiving, and distance from band to audience disappears. The venue’s aesthetic is functional and raw—no plush décor, just steel beams, strip lighting, and the echo of feedback.
Over the years, Sunburst has hosted diverse acts from all over Japan—punk, hardcore, rock — and its reputation for supporting underground scenes runs deep. It’s a proving ground for local talent and touring bands alike, the kind of space where the crowd, the stage, and the music bleed together in shared presence.
