arrival

When a new girl group emerges in the UK, the expectations are unfairly heavy. There’s the legacy of pop supremacy, the ghost of the Spice Girls’ cultural rule, the shadow cast by the Sugababes’ vocal complexity, the sleek futurism of FLO, and the growing wave of female collectives commandeering R&B, alt-pop, and club-leaning rhythms. Into this ecosystem storms XO, a four-piece whose debut EP, Fashionably Late, doesn’t sidestep the comparison pressure — it storms through it with the kind of intentional chaos that announces a new cultural presence.

Released via Polydor Label Group, the six-track project is less a formal debut and more a manifesto disguised as a sugar-coated explosion. XO have crafted an introduction rooted in pure girl-gang electricity: harmonies sharpened like acrylics, lyrics slung with the swagger of late-night cab rides, and production that bounces between R&B, UK house, punchy pop, and the early-internet cheekiness of Y2K mixtape culture.

Fashionably Late doesn’t hurry. It doesn’t apologise. It doesn’t aim for perfection. Instead, it arrives with the confidence of a group who know exactly why they’re here and exactly how loud they plan to get.

who

Girl groups in 2025 aren’t just about music — they’re ecosystems, visual languages, indie fashion references, meme-generation synergy, and the ability to control the velocity of excitement. XO understand this intuitively. Their aesthetic is part East London thrift maximalism, part glossy-editorial polish, part Tumblr rebellion revived with Gen-Z irony. They live between eras: early 2000s pop flare, late 2010s R&B precision, 2020s dance-pop grit, and the very-now mix of DIY authenticity and hyper-curation.

There’s also a strategic intelligence behind a debut titled Fashionably Late. It signals they know they’re entering a crowded space — but they’re entering at exactly the moment when mainstream pop desperately needs a new collective identity to champion. What FLO did for sleek, throwback R&B and what Boys World once hinted at for American pop is the lane XO appear ready to expand: messy, loud, emotionally sharp, choreography-ready but still grounded in believable personality.

Their vocals aren’t designed to blend into a single polished unit — they weave, interrupt, reinforce, and push. Their personalities feel drawn with thick ink: the firecracker, the sweetheart, the conceptualist, the wildcard. It’s classic pop architecture but interpreted through a 2025 lens where fans want multi-dimensional realness instead of manufactured gloss. XO give you both.

track one

The EP’s first track doesn’t act like an introduction — it acts like a declaration. Built on a bassline that sits somewhere between UKG nostalgia and late-night club euphoria, the opener is a sonic raised eyebrow: playful but direct. The verses move quickly, almost conversational, a style lifted from London street-pop and sharpened through R&B discipline.

Then the chorus hits: stacked harmonies, sugary high notes, and a rhythm that feels engineered for the perfect clip on TikTok but still holds weight in a live setting. It’s catchy without pandering, confident without arrogance. Most importantly, it’s the kind of song that establishes a world instantly. You know the colour palette. You know the vibe. You know XO aren’t here to ease you in — they’re here to declare presence.

track two

The second track is where XO reveal something crucial — emotional intelligence. It’s not a ballad in the traditional sense; it’s more like a diary entry set to pulsating synth pads. The production opens space, leaving room for vulnerability, but the songwriting keeps its edge. XO don’t do softness without bite.

Lyrically, the track navigates heartbreak with a sense of humour — a very British skill. “If you’re gonna leave, at least be stylish about it,” one member sings, half-mocking her own melodrama. It’s clever writing disguised as casual banter, the kind of line fans will quote in captions, on fan edits, in heartbreak playlists.

What’s refreshing is the cleanliness of the harmonies here. Each voice gets a moment, showcasing that XO aren’t leaning on production tricks to cover inexperience. They’re seasoned already.

track three

Every girl group with ambition needs a signature “we’re done, but we’re dancing anyway” track. XO deliver one with fire. It’s a two-minute punch — fast, fizzy, forward-moving. The percussion borrows from club music but cleans up at the edges, giving it a radio-ready polish.

The track’s hook is lethal: short, staccato, attitude-first. It’s less about heartbreak and more about reclaiming space. XO treat breakups like costume changes — dramatic, emotional, but ultimately empowering.

This is the moment on the EP where you can imagine the choreography: fast hands, fast footwork, hair flips timed to snare hits. It’s their future tour opener written in real time.

track four

Midway through the EP, XO step into a slightly experimental lane. Fans expecting wall-to-wall pop may be surprised by the textural shift — stripped percussion, breathy vocal layers, and a subtle trip-hop undertone that nods to Britain’s left-field lineage.

It’s the track that proves XO aren’t one-note. They understand mood. This is late-night introspection, the kind of song for headphones rather than speakers. It’s also where they experiment with vocal arrangement, letting certain members sit in gravelly lower registers while others float above the mix.

You can hear the influence of Charli XCX’s emotional futurism, of London’s slippery club textures, of early FKA Twigs minimalism — but ultimately, the track stays pop at its core. It’s an artistic risk that works because of the group’s confidence.

track five

Every breakout group secretly wants one track that becomes the fanbase’s flag. XO craft this intentionally. It’s upbeat, bright, written with chant-ready phrasing, and built around a sentiment so universal it fits every form of connection — friends, partners, group chats, DMs, late-night confessions.

This track feels engineered for community. The chorus invites participation; the bridges spotlight each member individually; the production sparkles with late-summer festival optimism. If the group’s TikTok videos, interviews, and behind-the-scenes energy are anything to go by, this song will be the heart of their fandom identity — the one that introduces their lightness, their humour, their sisterhood.

track six

The EP’s final track is the most surprising — not because it’s quiet, but because it’s self-aware. XO choose to end their debut project not with a shout, but with a smirk. The rhythm is understated; the lyrics are almost meta, acknowledging their arrival, the noise around them, and the expectations they’re about to disrupt.

There’s a sense of origin-story mythology being built. “We’re late, but we brought the party,” the hook jokes. “We’re the girls you’ll remember in the morning.” It’s cheeky, a little ironic, and very Gen-Z in its self-referentiality.

Ending with restraint rather than maximalism is a smart move — it signals longevity, not just hype. XO aren’t sprinting; they’re strategising. They’re debuting with clarity about where they want to go.

pro

One of the EP’s biggest strengths is the production team. You can hear the careful curation: a mix of major-label polish and up-and-coming UK soundmakers who bring edge, unpredictability, and youth.

The beats bounce between the following zones:
– Y2K R&B sparkle
– UK garage swing
– glossy electro-pop warmth
– post-internet club energy
– clean radio-format structure
– harmonically rich layering

XO’s sound feels familiar but never derivative. It’s the product of a team who understand that the next generation of girl-group pop must honour the classics while pushing for something new. Their producers clearly studied Little Mix, Destiny’s Child, TLC, En Vogue — but also PinkPantheress, Griff, Shygirl, and Kenya Grace.

This fusion is one of the reasons Fashionably Late lands with so much immediacy. It’s pop made with both history and hyper-present instincts.

energy

There’s a real appetite right now for collectives that feel like chosen families. Whether it’s boy bands reshaping masculinity, K-pop groups expanding narrative universes, or girl groups building online micro-cultures, youth culture is craving shared identity more than individual celebrity.

XO’s girl-gang branding taps directly into this. They feel like four best friends who know each other’s rhythms, annoyances, comedic timing, and emotional shorthand. They’re aspirational but not untouchable, stylish but not intimidating, polished but not artificial.

This accessibility — without sacrificing star power — is rare. It’s why Fashionably Late already feels sticky in the cultural moment.

why

Many groups play it safe on their first project. XO do the opposite: they declare their range immediately. The EP proves they can do attitude, humour, heartbreak, choreography-ready pop, experimental moodiness, and emotional precision — all while building a distinct sonic identity.

As a debut, it’s convincing because it doesn’t try to do everything. Instead, it shows the palette. The colours. The directions they could go. It’s a promise disguised as a party.

Most importantly, it’s consistent. The songwriting is sharp, the hooks land, the vocals hit, the production glows. It’s a cohesive opening chapter.

where

Based on Fashionably Late, several paths emerge for XO’s future:
A full album that leans into UK club heritage.
A darker, more conceptual project exploring the emotional textures hinted at in track four.
A tour-driven, choreography-heavy pop era.
Or a hybrid: glossy, anthemic, British-coded pop with a focus on big festival moments.

With Polydor behind them and a clear creative vision in front of them, XO have space to experiment.

What’s most exciting is that the group doesn’t feel locked into one identity. They aren’t boxed into “the cool R&B girl group” or “the pop darlings.” They can shift lanes, pull influences from anywhere, and still maintain cohesion — because their chemistry is the glue.

fin

There’s something thrilling about a debut that doesn’t just announce the arrival of an act, but the beginning of a new cultural micro-wave. XO’s Fashionably Late is exactly that: a high-voltage, personality-rich, emotionally sharp, meticulously crafted introduction to a group built for longevity.

In six tracks, XO prove they belong in the lineage of British pop’s most exciting girl collectives — not as imitators, but as modern successors. They’re fun, fierce, clever, stylish, sonically adventurous, and deeply charismatic.

If this is them showing up “late,” then the rest of the industry better brace for what happens when XO decide to take their time.
