"Right now in 2021, everyone's doing everything," Chris Martin remarked to Apple Music’s Zane Lowe while promoting Coldplay's ninth album, Music of the Spheres. "You can like Olivia Rodrigo as much as you like AC/DC and no one thinks that's weird. And that's musical utopia for me ... It's miraculous. So why would you want to stay in one box?"

It's this willingness to break the boundaries of the traditional guitar band setup that's helped Coldplay maintain relevance for the best part of 25 years.

The Londoners first caught attention at the turn of the century riding the post-Britpop wave. But while most of their peers failed to sustain their early momentum as the decade progressed, the "Yellow" hitmakers flourished.

In the studio, Martin, guitarist Jonny Buckland, bassist Guy Berryman, and drummer Will Champion continually challenged the notions of indie rock, tapping up everyone from Brian Eno to Max Martin to help fulfil their creative vision. Simultaneously, they also grew in confidence on the live stage, their ability to emotionally connect on a grand scale with equally grand songs eventually challenging U2 as the world's must-see stadium act.

The stats speak for themselves, too: more than 100 million album sales, 10 consecutive UK No. 1s, and seven GRAMMY wins. And they're still very much at the top of the game, as 2024's Moon Music reached pole position in 16 countries and their latest tour set the record for the highest attendance of all time.

Viral kiss cams aside, the Music of the Spheres World Tour sold 11.4 million tickets as of press time, the most of any artist in history. And to close out their momentous run, they'll play 10 sold-out shows at London's Wembley Stadium from Aug. 22 to Sept. 8.

As the band wrap up their record-breaking trek, here's a look at the all-conquering quartet's musical evolution.

The Indie Favorite

Coldplay might now be renowned as chart-topping, LED-flashing stadium rock giants. But their debut album's artwork alone highlighted how they started out in much more humble fashion. Iconic as it became, the front cover was taken on a disposable Kodak camera, with the spinning yellow globe costing 10 English pounds. And the sounds within were equally low-key.

Largely co-produced with Ken Nelson, Parachutes could occasionally get loud (see the jagged indie-rock of "Shiver"). But highlighted immediately by hushed opener "Don't Panic," it was undeniably defined by the double whammy of Buckland's ethereal chiming guitars and Martin's intimate tones.

Standout "Trouble" remains one of the latter's finest vocal displays, his initial world-weary resignation giving way to impassioned pleas before showcasing the kind of fragile falsetto that made Jeff Buckley a cult hero. Breakout hit "Yellow," recent TikTok favorite "Sparks," and "We Never Change" all harnessed Martin's uncanny ability to heighten the emotions with sentiments that were almost willfully oblique.

As a result, Coldplay hoovered up the post-Britpop audience that had been left bewildered by Radiohead's experimental Kid A, ultimately spearheading Parachutes to the UK No. 1 spot, worldwide sales of at least eight million, and their first GRAMMY for Best Alternative Music Album. A new group of sensitive stars were born.

The World-Beaters 

Perhaps burned by Oasis manager Alan McGee referring to them as bedwetters, Coldplay abandoned the politeness and timidity of their debut for follow-up A Rush of Blood to the Head, a much more confident LP that suggested they had one eye firmly on stealing U2's "biggest band in the world" crown.

Loud and proud opener "Politik" immediately made it clear they meant business. And from the surging "God Put A Smile Upon Your Face" to the nervy existentialism of "A Whisper," the second consecutive Best Alternative Rock Album GRAMMY winner had a similar sense of urgency throughout.

There were still plenty of quieter moments, of course. The acoustic country rock of "Warning Sign" paid homage to Johnny Cash. Martin audibly pined for his lost love on the stunning, swelling ballad "The Scientist." And Record Of The Year-winning "Clocks" possessed one of the decade's most hypnotic piano motifs.

The quartet had to work hard, though, to stay on top of indie-rock's new premier league with their third studio effort, X&Y. By this point, the similarly melancholic Keane and Snow Patrol had started to snap at their heels, while a second wave of Britpop, including Razorlight and Kaiser Chiefs, were offering a much rowdier alternative.

That perhaps explains why the record had such a difficult conception: the band not only discarded more than 50 songs they believed weren't up to scratch, but sacked regular producer Nelson in favor of their mixer Danton Supple.

Still, the behind-the-scenes troubles weren't particularly evident on another self-assured affair designed for mass consumption. Buoyed by the gleaming "Speed of Sound" and gospel-tinged "Fix You," X&Y went on to top the charts in 32 countries including the U.S., became the best-selling album of 2005 worldwide, and earned Coldplay their first Best Rock Album GRAMMY nomination.

While the group largely stuck to their winning formula, there were hints of the reinvention that lied ahead. Maverick Brian Eno provided the synths on "Square One," while there were inspired samples of Kraftwerk's "Computer Love" and the theme to Stanley Kubrick's A Space Odyssey. Coldplay have repeatedly dismissed the album as their weakest since its 2005 release, but it still stands up to most of their peers' best.

The Creative Leaps

"I don't care if we sell a million less records," Martin declared while promoting Coldplay's fourth LP, Viva la Vida or Death and All His Friends — a statement that hinted the band had ditched the formula that propelled them to the top of the charts. In the end, the album ended up shifting similar numbers, securing their first Album Of The Year GRAMMY nomination, and spawning their first No. 1 on both sides of the Atlantic.

Viva La Vida and Death To All His Friends isn't quite as revolutionary as its Les Misérables -inspired cover art (and the band's matching uniforms) implied. Bittersweet melodies, universal platitudes and epic woah-oh choruses are still very much the order of the day. However, with Eno — the man who took Coldplay's heroes U2 to another musical plain — fully at the helm, the group's template is given a much richer texture.

There are flourishes of worldbeat, art rock and orchestral pop throughout, with seven-minute epics "Yes" and "Lovers in Japan/Reign of Love" giving chances for Martin to further show off his newfound baritone and each bandmate to flex their musical muscles. The biggest curveball, however, from a group renowned for their abstract lyrical themes is "Violet Hill," a booming protest song apparently aimed at the evils of Fox News ("When the future's architectured/ By a carnival of idiots on show"). This was still Coldplay, but not quite as we knew them.

They pushed the conceptual levels even further with its follow-up, Mylo Xyloto, a rock opera that depicted a love story amid a war against color and sound on a totalitarian planet named Silencia. On paper, it sounded like the kind of post-apocalyptic opus you'd expect from the world of '70s prog. Instead, it was a melting pot of electronica, new wave and R&B-tinged pop every bit as colorful as its graffiti cover art.

This is where Coldplay truly distanced themselves from their indie-rock roots and made a concerted bid to maintain chart relevance. The percussive banger "Every Teardrop Is a Waterfall" and soaring festival anthem "Paradise" gave them back-to-back Top 20 hits in the U.S. for the first time in their career, while the Rihanna-featuring "Princess of China" kickstarted their penchant for superstar collaborations.

By the end of its campaign, they'd added a further five nods to their GRAMMY tally. And if you're wondering how all the dystopian drama ended, well, of course, the two lovebirds saved the day.

The Breakup Album

The recruitment of superstar DJs Avicii and Madeon, not to mention innovative beatmaker Timbaland, suggested that Ghost Stories would be a maximalistic hands-in-the-air affair. Conversely, it proved to be the most downbeat and stripped back album of Coldplay's career thus far.

Penned in the wake of Martin's split from actress Gwyneth Paltrow, the Best Pop Vocal Album GRAMMY nominee eschewed the band's trademark optimism for songs of despair and heartbreak, with only the slow-building EDM-adjacent "A Sky Full of Stars" providing a sense of euphoria. "There's only so far you can go without becoming pompous and a bit overblown," Champion acknowledged about removing the playful excesses of their previous two records.

Ghost Stories might be short of songs you can sing along to in the shower, but it's the four-piece at their most evocative. Based on an unreleased soundscape from electronic maestro Jon Hopkins, "Midnight" is a gorgeous piece of beatless ambience with ghostly melodies that appear to drift in and out of the ether. Elsewhere, the beautifully meditative "Magic" remains one of the band's most interesting builds, its initially unassuming charms slowly unfolding with each listen.

Gossip hounds looking for clues into all the divorce drama would have been found wanting — although drawing upon far more personal themes, Martin's lyrics still keep specifics at arm's length. But with its intimacy, wistfulness and inherent sense of loss, Ghost Stories is still worthy of joining the canon of pop's great breakup albums.

The All-Star Epics

Following the muted palette of Ghost Stories, Coldplay went full-on Technicolor for their seventh album, A Head Full of Dreams, literally — both in the accompanying tour that established their penchant for pyrotechnics, lasers and glow-in-the-dark wristbands, and with a couple of on-the-nose track titles like "Kaleidoscope" and "Colour Spectrum." And they utilized a whole host of star names to further heighten the razzmatazz.

Having previously worked with Jay-Z on an alternative version of "Lost!," the quartet tapped his other half Beyoncé to provide vocals on three numbers including the soaring "Hymn for the Weekend." Noel Gallagher, the proud rocker who you wouldn't necessarily expect to gravitate toward such a famously polite outfit, beefs up the guitars on "Up and Up."

There are also contributions from Scandi-pop favorite Tove Lo, gospel legend Merry Clayton, and perhaps most surprisingly of all, Martin's Oscar-winning ex-wife. Proving that their split was of the amicable kind, Paltrow pops up on her own piano-led tribute number "Everglow," in which Martin gushes "This particular diamond was extra special" on the opening verse.

While that song is firmly rooted in the Coldplay of old, hit factory Stargate — who has worked with Rihanna, Katy Perry and pretty much every other major chart act of the 21stcentury — continually pushed the Brits into new shinier pop territory on the rest of the album. Had A Head Full of Dreams turned out to be the band's swansong as Martin purported, they'd have gone out on one dazzling high.

As it turned out, Coldplay wasn't done, returning with Everyday Life four years later. But while that album traded star power for genre exploration (more on that later), they went back to the collaborative approach for 2021's AOTY GRAMMY-nominated Music of the Spheres. The quartet roped in Selena Gomez on the sobering ballad "Let Somebody Go," musical wunderkind Jacob Collier and We Are KING on the a cappella "Human Heart," and K-Pop sensation BTS on the infectious "My Universe."

But perhaps the most notable appointment was Max Martin, the hitmaking machine with 24 U.S. chart-toppers and counting to his name. Hailed by the band as a "true wonder of the universe," the Swede stamped his melodic mark throughout an unwaveringly optimistic record that pondered the existence of humanity in outer space.

With each of its nine full-length tracks designed to represent a fictional planet, satellite or star, Music of the Spheres certainly committed fully to its intergalactic theme — so much so that lead single "Higher Power" was beamed into the International Space Station. The majestic closer "Coloratura" (which recalls Pink Floyd in their celestial prime), the gleaming astral electronica of "Infinity Sign," and the handful of ambient instrumental interludes also helped immerse listeners in their lands of make believe. Yet it's the killer pop hooks and considered collaborative spirit that sent this sci-fi spectacular sky high.

The Boundary Pushers

Recorded in places as far-flung as Los Angeles, Tuscany and Johannesburg, Coldplay's eighth LP, Everyday Life, was inevitably informed by its surroundings. "Arabesque" is a swaggering burst of desert blues boasting three gifted members of Fela Kuti's dynasty. "Bani Adam" pairs a medieval Persian poem with neo-classical piano and African choral music. And like Vampire Weekend before them, "Orphans" takes the syncopated worldbeat of Paul Simon's Graceland and gives it a 21st century sheen. Everyday Life's unique worldwide premiere, a full live performance against the backdrop of Jordan's Amman Citadel, made total sense.

Split into two sides — Sunrise and Sunset — the creatively restless double album also found room to sample Janis Joplin, Alice Coltrane and the late Scottish indie cult hero Scott Hutchison. And the quartet were so keen to show off their new-found freewheeling spirit they even included a demo. "I haven't finished that one yet," Martin admits on the stripped-back folk of "WOTW/POTP."

It's not just musically where Coldplay expanded their horizons, though. Previously famed for their aversion to all things socio-political, the band suddenly tackled everything from firearm control ("Guns") to the systematic racism within the American police force ("Trouble in Town"). Meanwhile, the hymnal title track, Buddhist-referencing doo-wop of "Cry Cry Cry," and finger-clicking gospel of "BrokEn" saw Martin delve much deeper into themes of faith and spirituality than ever before. And in a first for the band, there's not just one but three uses of profanity.

Despite proudly deviating from their winning formula, Everyday Life still gave Coldplay an eighth consecutive UK No. 1 and a second GRAMMY nod for Album Of The Year.

2024's Moon Music might not have been as globe-trotting — although it does feature talents from Argentina, Chile, Palestine, and Nigeria — but it was no less eclectic. It veered from Balearic electronica ("AETERNA") and The Beatles-esque pop ("ALL MY LOVE") to sprightly disco-funk ("GOOD FEELINGS") and sweeping symphonies ("ONE WORLD") during a loose narrative journey once again based in deep space.

Perhaps the album's most impactful track is "WE PRAY," a defiant burst of alternative hip-pop which brings together Burna Boy, Little Simz, Elyanna, and Tini for a life-affirming ode to the power of prayer, and the acoustic "JUPITER," an "it gets better" message of hope to a teenage girl struggling with her sexuality.

"There's never been an easier time to give up, and so this is a record about not doing that," Martin explained about its glass half-full approach. Indeed, Moon Music cemented Coldplay's evolution from masters of indie melancholy to pop's ultimate spirit-lifters.
