By choosing โPARTY PEOPLE,โ B&ZAI deliberately reshaped a familiar SixTONES track into a live-band showcase, placing Rei Yabanaโs bass at the center of the sound. What unfolds is a heat-soaked moment of trust, musicianship, and confidence: a young group proving exactly who they are when the lights are brightest. This performance is more than a festival clipโitโs a statement.
There is a specific kind of alchemy that happens when the understated collide with the scorching sun, a transformation where hidden energy bursts forward to rival the heat of the day.
B&ZAIโRyo Hashimoto,ย Rei Yabana,ย Taiki Konno,ย Rinne Sugeta,ย Katsuki Motodaka,ย Yujin Suzuki,ย Hoshiki Kawasaki, andย Michiharu Inabaโcarries the self-proclaimed title of “B-Minor”โa playful term they use to describe themselves as the quiet, slightly reserved type, much like the musical key known for its moody, introspective feel. Itโs a way of saying they see themselves as lowโkey and understated offstageโbut their performance of “PARTY PEOPLE” at the OSAKA GIGANTIC MUSIC FESTIVAL 2025 proves that when the stage lights hit them, they donโt just reflect the light; they generate their own blinding incandescence.
Even as the real world settles into the chill of December, this performance exists as a sanctuary of eternal summer. It functions like a digital fireplaceโone that draws people back instinctively, inviting them to warm their hands against the memory of 34โdegree heat and relentless sunlight. The temperature never seems to drop here. What unfolds on screen is not simply a cover of a beloved SixTONES track, but a crescendo shaped by atmosphere, intent, and identityโsomething that feels entirely, unmistakably B&ZAI.
The magic begins with the rhythm. If the original track is a wave, B&ZAIโs version is the undertow, driven by a bassline so potent it seems to vibrate through the screen. Rei Yabana, their self-assigned bandmaster, stands at the center of this sonic shift, his bass performance acting less like an accompaniment and more like a second vocalistโgrowling, melodic, and undeniably cool.
There is a palpable sense of trust on display here; you can almost feel the moment the other members stepped back to let Rei take the wheel, confident that his musicianship would hook the audience instantly. It is a “Super Yabana Time” that electrifies the air, turning a dance anthem into a rock-infused declaration of intent.
This instrumental grit is matched only by the raw honesty of their vocals. In the unforgiving environment of an outdoor festival, there is nowhere to hide, yet every member delivers with a stability that betrays their “Junior” status. The voices are distinct and unfiltered, cutting through the humidity with a live power that has earned the nod of approval from even the most devoted SixTONES fans.
There is a profound respect for the original artists in their deliveryโSixTONES being their close comrades and respected seniorsโbut there is also a refusal to simply mimic; instead, they dye the song in their own colors, proving that they possess the musical chops to stand on any stage, no matter how large.
Perhaps the most captivating element, however, is the sheer โgapโ at play. These are young men who often joke about their gloomy or indoor nature, existing somewhere in a figurative pianissimo offstageโrestrained, introspective, almost hushed.
Even after watching their RIDE ON TIME episodes, this contrast rings true: on stage, they shine so brightly it becomes easy to forget how human and grounded they are behind the scenes. This quietness is not born from shyness or melancholy, but from a mature, inward-looking respect for their craftโa seriousness that comes with understanding the weight of the work they do.
They joke, they fool around, but underlying it all is diligence. In that sense, โBโMinorโ is never a flaw; it is simply another chord in their progression, one that deepens the harmony and allows their soundโand their storyโto grow richer with every performance. Yet the moment they step into the spotlight, the performance swells into a full-bodied crescendo.
Draped in the trappings of summer kings, they command the crowd with water guns and fearless smiles, their energy rising measure by measure until it fills the entire space. It is a deliberate contrast: the soโcalled โBโMinorโ introverts modulating seamlessly into something bold and extroverted, not through chaos, but through control.
But at the heart of everythingโevery reaction, every replay, every lingering sense of heat long after the festival endedโstands Rei. This performance wasnโt just a cover; it was constructed as a showcase. A deliberate, thoughtful decision by the members to choose a song where the bass isnโt just supportive, but transformative. โPARTY PEOPLEโ becomes an entirely different creature in B&ZAIโs hands because it is shaped around the depth, color, and imagination of his playing.
Rei occupies a rare position within the groupโone shaped as much by study as by experience. Balancing his idol career alongside formal musical education, he carries what he learns in the classroom directly onto the stage, allowing theory and practice to inform one another in real time. This dual perspective lends him a grounded clarity: an understanding that technical growth never truly ends, no matter how early success might suggest otherwise. Even after stepping into professional spaces at a young age, being surrounded by peers of equal talent in an academic setting reinforces a sense of humilityโan awareness that mastery is something pursued, not claimed.
This outlook quietly defines one of his greatest strengths. There is something disarmingly human about Rei’s presence: relatable in his curiosity and diligence, yet unmistakably exceptional in execution. His proficiency extends well beyond the bass alone, making him indispensable not only as a performer but as an architect of soundโsomeone capable of shaping arrangements, refining structure, and guiding the overall musical direction of the band.
Stepping into the role of bandmaster, he assumes responsibility with the calm focus of a conductor at the center of an orchestra. If accountability must fall on someoneโs shoulders, he accepts it without hesitationโnot out of ego, but out of commitment. By keeping close watch over every musical detail, he holds himself to the same standard he sets for the group. It is this combination of discipline, humility, and care that anchors the performance: a quiet authority that ensures nothing is rushed, nothing is wasted, and nothing is taken lightly.
His playing isnโt flashy for the sake of spectacle; itโs crafted, intentional, and deeply respected by both his group and the fans watching. The trust placed in him is palpableโnot only during the solo but in every bar of the song. The performance feels like a declaration of what B&ZAI can become because of him: a group whose identity is intertwined with live musicianship, whose sound is shaped not from backing tracks but from the hands of its own members.
And that’s why the bass doesnโt simply anchor the track here; it narrates it, bringing the instrument that is often overlooked to the forefront. Rei threads together melody and rhythm with a style that feels simultaneously technical and emotionalโan approach that many noted immediately, even those unfamiliar with him. His tone cuts through the humid air with clarity, carving out a sonic pathway that the rest of the group instinctively follows.
You can sense how much the performance was built around him: the way the members step back at the right moment, how their expressions shift as if presenting him, how the entire energy funnels toward that bass-led drop that makes the crowd erupt.
This is why the performance carries such weight. It isnโt simply that Rei played wellโitโs that the entire staging acknowledges and elevates him. Itโs that they chose a song explicitly because it would let his bass speak at full volume. Itโs that audiences from every corner of the fandom spectrum walked away remembering the bassist first, not because they were told to, but because the music demanded it.
The video captures more than just a song; it captures a pivotal summer memory that refuses to fade. The audience, standing under the blazing sun without shade, mirrors the intensity coming from the stage, creating a feedback loop of energy that feels miraculous.
And underlying all of this is pride. Not just from their own fans, but from those who came from other groups and found themselves unexpectedly moved or impressed. There is a growing belief that B&ZAI is no longer a group people stumble uponโtheyโre a group people seek out. A group whose growth is already visible performance to performance. A group that, despite being new, carries itself with the kind of purpose and craftsmanship that suggests longevity.
For the viewers watching now, wrapped in blankets and facing the winter cold, this performance serves as a reminder of a hotter, brighter season. It is a place to return to when the days get short, a source of power from a group that is rapidly outgrowing their “minor” label to become major players in the light.
B&ZAI has proven that they can turn a borrowed song into a personal anthem, bridging fandoms and seasons alike.
