Mercury Lounge shimmered beneath the slow spin of a disco ball this past Tuesday night, the mirrored light scattering across the room like fragments of anticipation. The grungy Lower East Side venue – long known for cradling artists just before they outgrow its walls – transformed into something softer, almost dreamlike: a glittering dance floor where the only rule was to raise your hands, surrender to the moment, and simply exist. That is the atmosphere Alex Sampson creates the instant he glides onstage: a world where hopeless romantics feel understood and emotional vulnerability isn’t suppressed, but rather fantasized.

His songs arrive wrapped in a sentimental maturity that feels years older than he is. At just 22, Sampson sings with the emotional clarity of someone who has already learned how fleeting moments can be, pulling at heartstrings in a way that makes audiences sing not just because they know the lyrics, but because they recognize themselves inside them. Mercury Lounge has always been a checkpoint for artists on the verge of something larger, and watching Sampson perform felt like witnessing one of the final intimate chapters before arenas replace dim stage lights. He is standing on that threshold now, and it feels inevitable that soon his name will no longer be a discovery but a necessity.

Rushing from my Tuesday afternoon shift, I slipped into the venue just as direct support Mary Jo settled onto the stage, missing the first opener but arriving in a room already alive with anticipation. The crowd had filled in quickly, proving this wasn’t simply an audience waiting for a headliner, but one eager for a full evening of connection. Pairing Mary Jo with Alex Sampson felt almost celestial: two artists existing comfortably in emotional honesty rather than spectacle.

Dressed casually in baggy clothes, sweatpants and a jersey, Mary Jo immediately dissolved the invisible barrier between performer and audience, and it stayed collapsed throughout the rest of the show. Sitting with her knees pulled to her chest, she turned the room into something intimate – less concert, more living room gathering, like friends circling a campfire while familiar melodies flicker back to life. Her banter felt effortless and warm, inviting the crowd into the performance rather than placing them outside of it.

At one point, she launched into Paramore’s “Still Into You,” pulling audience members onstage for a spontaneous dance party and flipping the microphone toward the front row so voices blended into one collective chorus. It didn’t feel rehearsed; it felt shared. Having missed her Warped Tour set months earlier, finally seeing Mary Jo live confirmed what many already suspect: she is an artist to watch closely. Her vocals drift between airy highs and raspy confessionals, and her stage presence – already confident so early in her career – fosters something deeper than engagement. It feels communal, almost familial, like everyone in the room briefly belongs to the same story.

As the lights dimmed again, the vigor shifted with them. The crowd skewed young, yet parents dotted the room beside their children, not as chaperones, but as participants. They danced together, lifted kids onto their shoulders for better views, and smiled through lyrics they may have only recently learned. Watching generations share the same space felt quietly moving – proof that music dissolves age, replacing it with shared memories. For a moment, strangers became companions bound by melody.

When Alex Sampson finally bounced onto the stage – fashionably late, anticipation stretched thin in the best way – the room erupted. Any remaining hesitation disappeared instantly. There’s something disarmingly genuine about him: he doesn’t polish away his youth or sand down his personality for perfection. Instead, he leans into it, radiating an infectious energy that makes resistance impossible.

Having seen Sampson perform in Brooklyn before, this set felt markedly elevated. Gone was any sense of an artist still finding footing: this was a headliner fully stepping into his space. Mercury Lounge suddenly felt too small to contain the momentum he carried, as he moved endlessly from one corner of the stage to another, voice soaring effortlessly without missing a beat. Even in moments when an acoustic guitar rested over his shoulder, he remained in constant conversation with the crowd: eye contact, smiles, gestures acknowledging every ounce of love thrown his way.

There’s an undeniable pop-star quality to Sampson, one that calls back to early-era Justin Bieber – the heartthrob energy paired with vocals strong enough to silence skepticism. What captivates isn’t just charisma, but musicianship: songs that feel like captions to the moments people remember most, the quiet transformations and late-night realizations that define growing up.

Mercury Lounge may only be a single stop along his journey, but it marked a noticeable leap from the last time I saw him perform. The intimacy of the venue made the night feel fleeting, like catching lightning before it escapes into a larger sky. If Tuesday proved anything, it’s that Alex Sampson is no longer approaching the brink; he’s already stepping across it.

And as 2026 unfolds, it feels less like wondering where he’ll go next, and more like waiting to see just how far the story will carry him.
