Formation and first years (1996 - 99)

Chris Martin and Jonny Buckland first met during their orientation week at University College London (UCL) in September 1996. The pair spent the rest of the university year planning a band, ultimately forming a group called Pectoralz. Guy Berryman, a classmate of Martin and Buckland, later joined the group. By 1997, the group, who had renamed themselves Starfish, performed gigs for local Camden promoters at small clubs. Martin also had recruited his longtime school friend Phil Harvey, who was studying classics at Oxford, to be the band's manager. Coldplay have since accepted Harvey as the fifth member of the group. The band's line-up was completed when Will Champion joined to take up percussion duties. Champion had grown up playing piano, guitar, bass, and tin whistle; he quickly learned the drums (despite having no previous experience). The band finally settled on the name "Coldplay" which was suggested by Tim Crompton, a local student who had been using the name for his group. By 1997, Martin had also met then Classics student Tim Rice-Oxley. During a weekend on Virginia Water, they asked each other to play off their own songs on the piano. Martin, finding Rice-Oxley to be talented, asked him to be Coldplay's keyboard player but Rice-Oxley refused as his own band, Keane, was already operational. Days after, this event would shape the second line-up of Keane and keep Coldplay's unaltered, thus leaving both bands as quartets.

In 1998, the band released 500 copies of the Safety EP. Most of the discs were given to record companies and friends; only 50 copies remained for sale to the public. In December of that year, Coldplay signed to the independent label Fierce Panda. Their first release was the three-track Brothers and Sisters EP, which they had quickly recorded over four days in February 1999.

After completing their final examinations, Coldplay signed to Parlophone for a five-album contract in early 1999. After making their first appearance at Glastonbury, the band went into studio to record a third EP titled The Blue Room. Five thousand copies were made available to the public in October, and the single "Bigger Stronger", received BBC Radio 1 airplay. The recording sessions for The Blue Room were tumultuous. Champion was briefly fired from the band, but Martin later pleaded with him to return after kicking him out, and because of his guilt, went on a drinking binge. Eventually, the band worked out their differences and put in place a new set of rules to keep the group intact. Inspired by bands like U2 and R.E.M., Coldplay decided that they would operate as a democracy (and that profits would be shared equally). Additionally, the band determined they would fire anyone who used hard drugs.

Parachutes (1999 - 2001)

The band initially planned to record their debut album in the space of two weeks. However, tours and other live performances caused the recording to spread out between September 1999 and April - May 2000. The album was recorded at Rockfield Studios, Matrix Studios, and Wessex Sound Studios with producer Ken Nelson, although the majority of Parachutes' tracks were recorded at Liverpool's Parr Street Studios (where they accessed three studio rooms). The mixing process on all songs for the album was done by American engineer Michael Brauer in New York. During that period, they played on the Carling Tour, which showcased up-and-coming acts.

After releasing three EPs without a hit song, Coldplay sparked their first Top 40 hit with the lead single from Parachutes, "Shiver", released in March 2000 to a number 35 peak position on the UK Singles Chart.

June 2000 was a pivotal moment in Coldplay's history: the band embarked on their first headlining tour, including a showing at the Glastonbury Festival. The band also released the breakthrough single "Yellow". Having the role as Coldplay's first release to crack the top five, the song shot to number four on the UK Singles Chart and placed Coldplay in public consciousness. "Yellow" and "Shiver" were initially released as EPs in the spring of 2000. The former was later released as a single in United Kingdom on 26 June 2000. In the United States, the song was released as the lead single off the then-untitled debut album. In October 2000, the track was sent to US college and alternative radio outlets.

Coldplay released their first studio album, Parachutes, on 10 July 2000 in the United Kingdom via their record label, Parlophone. The album debuted at number one on the UK Albums Chart. It was released on 7 November 2000 by record label Nettwerk in North America. The album has been made available on various formats since its initial release; both Parlophone and Nettwerk released it as a CD in 2000, and it was also released as a cassette by new US label Capitol in 2001. In the following year, Parlophone issued the album as an LP.

The band released a limited-edition CD of "Trouble", the third single off the album, which features a remix of "Yellow". It was pressed to 1,000 copies, and was issued only to fans and journalists Both "Yellow" and "Trouble" earned regular radio airplay in the UK and US.

Parachutes was nominated for the Mercury Music Prize in September 2000. Having found success in Europe, the band set their sights on North America, by releasing the album there in November 2000, and started the U.S. Club Tour in February 2001. Although Parachutes was a slow-burning success in the United States, it eventually reached double-platinum status. The album was critically well-received and earned a Best Alternative Music Album honours at the 2002 Grammy Awards. Chris Martin claimed, after the release of Parachutes, that the album's success was intended to elevate the band's status as the "biggest, best band in the fucking world."

A Rush of Blood to the Head (2001 - 04)

After the success of Parachutes, Coldplay returned to the studio in September 2001 to begin work on their second album A Rush of Blood to the Head, once again with Ken Nelson producing. Since the band had never stayed in London before, they had trouble focusing. They decided to relocate in Liverpool, where they recorded some of the songs on Parachutes. Once there, vocalist Chris Martin said that they became obsessed with recording. "In My Place" was the first song recorded for the album. The band released it as the album's lead single because it was the track that made them want to record a second album following a "strange period of not really knowing what we were doing" three months after the success of Parachutes. According to Martin "one thing kept us going: recording 'In My Place'. Then other songs started coming."

The band wrote more than 20 songs for the album. Some of their new material, including "In My Place" and "Animals", was played live while the band was still touring Parachutes. The album's title was revealed through a post on the band's official website. The album was released in August 2002 and spawned several popular singles, including "In My Place", "Clocks", and the ballad "The Scientist". The latter was inspired by George Harrison's title track to All Things Must Pass, which was released in 1970.

Coldplay toured from June 2002 to September 2003 for the A Rush of Blood to the Head Tour. They visited five continents, including co-headlining festival dates at Glastonbury Festival, V2003 and Rock Werchter. Many concerts showcased elaborate lighting and individualised screens reminiscent of U2's Elevation Tour and Nine Inch Nails' Fragility Tour. During the extended tour, Coldplay recorded a live DVD and CD, Live 2003, at Sydney's Hordern Pavilion.

In December 2003, readers of Rolling Stone chose Coldplay as the best artist and the best band of the year. At that time the band covered The Pretenders' 1983 song "2000 Miles" (which was made available for download on their official website). "2000 Miles" was the top selling UK download that year, with proceeds from the sales donated to Future Forests and Stop Handgun Violence campaigns. A Rush of Blood to the Head won the Grammy Award for Best Alternative Music Album at the 2003 Grammy Awards. At the 2004 Grammy Awards, Coldplay earned Record of the Year for "Clocks".

X&Y (2004 - 06)

Coldplay spent most of 2004 out of the spotlight, taking a break from touring and releasing a satire music video of a song from a fictional band titled The Nappies while recording their third album. X&Y was released in June 2005 in UK and Europe. This new, delayed release date had put the album back into the next fiscal year, actually causing EMI's stock to drop. It became the best-selling album of 2005 with worldwide sales of 8.3 million. The lead single, "Speed of Sound", made its radio and online music store debut on 18 April and was released as a CD on 23 May 2005. The album jettisoned onto its original chart entry at the number one position in 20 countries worldwide, and was the third-fastest selling album in UK chart history. Two other singles were released that year: "Fix You" in September and "Talk" in December. Critical reaction to X&Y was mixed, though less enthusiastic than that of its predecessor. New York Times critic Jon Pareles describing Coldplay as "the most insufferable band of the decade", whereas Pitchfork Media rated it "4.9/10.0" and called it "...bland but never offensive, listenable but not memorable." Comparisons between Coldplay and U2 became increasingly common. Chris Martin later revealed that the reviews that ranged from mixed to negative, note-worthy for their remarks on comparing it to U2's How to Dismantle an Atomic Bomb (2004), made him feel "liberated".

From June 2005 to July 2006, Coldplay went on their Twisted Logic Tour, which included festival dates like Coachella, Isle of Wight Festival, Glastonbury and the Austin City Limits Music Festival. In July 2005, the band appeared at Live 8 in Hyde Park, where they played a rendition of The Verve's "Bitter Sweet Symphony" with Richard Ashcroft on vocals. In September, Coldplay recorded a new version of "How You See the World" with reworked lyrics for War Child's Help!: A Day in the Life charity album. In February 2006, Coldplay earned Best Album and Best Single honours at the BRIT Awards. Two more singles were released during 2006, "The Hardest Part" and "What If". The sixth and final single, "White Shadows" was released in Mexico during June 2007.

Viva la Vida or Death and All His Friends (2006 - 2009)

In October 2006, Coldplay began work on their fourth studio album, Viva la Vida or Death and All His Friends, with producer Brian Eno. Taking a break from recording, the band toured Latin America in early 2007, performing in Chile, Argentina, Brazil, and Mexico. After recording in churches and other venues in Latin America and Spain during their tour, the band said the album would likely reflect Hispanic influence. The group spent the rest of the year recording with Eno.

Martin described Viva la Vida as a new direction for Coldplay: a change from their past three albums, which they have referred to as a "trilogy". He said the album featured less falsetto as he allowed his voice's lower register to take precedence. Some songs, such as "Violet Hill", contain distorted guitar riffs and bluesy undertones.

"Violet Hill" was confirmed as the first single, with a radio release date of 29 April 2008. After the first play, it was freely obtainable from Coldplay's website from 12:15 pm (GMT +0) for one week (achieving two million downloads), until it became commercially available to download on 6 May. "Violet Hill" entered the UK Top 10, US Top 40 (entering the Top 10 in the Hot Modern Rock Tracks chart) and charted well in the rest of the world. The title track, "Viva la Vida", was also released exclusively on iTunes. It became the band's first number one on the Billboard Hot 100, and their first UK number one, based on download sales alone.

Upon release, Viva la Vida or Death and All His Friends topped the UK album chart, despite having come on the market only three days previously. In that time, it sold 302,000 copies; the BBC called it "one of the fastest-selling records in UK history". By the end of June, it had set a new record for most-downloaded album ever. In October 2008, Coldplay won two Q Awards for Best Album for Viva la Vida or Death and All His Friends and Best Act in the World Today. The band followed up Viva la Vida or Death and All His Friends with the Prospekt's March EP, which was released on 21 November 2008. The EP features tracks from the Viva la Vida or Death and All His Friends sessions and, as well as being available on its own, was issued as a bonus disc with later editions of Viva la Vida or Death and All His Friends. "Life in Technicolor II" was the only single released from the EP.

Coldplay began their Viva la Vida Tour in June, with a free concert at Brixton Academy in London. This was followed two days later by a 45-minute performance that was broadcast live from outside BBC Television Centre. Released in late 2008, "Lost!" became the third single from the album, featuring a new version with Jay-Z. After performing the opening set on 14 March 2009 for Sound Relief at the Sydney Cricket Ground, Coldplay headlined a sold-out concert later that same night. Sound Relief is a benefit concert for victims of the Victorian Bushfire Crisis and the Queensland Floods.

On 4 December 2008, Joe Satriani filed a copyright infringement suit against Coldplay in the United States District Court for the Central District of California. Satriani's suit asserts that the Coldplay song "Viva la Vida" includes "substantial original portions" of the Satriani song "If I Could Fly" from his 2004 album, Is There Love in Space?. The Coldplay song in question received two Grammy Awards for "Song of the Year." The band denied the allegation. An unspecified settlement was ultimately reached between the parties.

Coldplay were nominated for four BRIT Awards in 2009: British Group, British Live Act, British Single ("Viva la Vida") and British Album (Viva la Vida or Death and All His Friends). At the 51st Grammy Awards in the same year, Coldplay won three Grammy Awards in the categories for Song of Year for "Viva la Vida", Best Rock Album for Viva la Vida or Death and All His Friends, and Best Vocal Pop Performance by a Duo or Group for "Viva la Vida".

A live album entitled LeftRightLeftRightLeft was recorded at various shows during the tour. LeftRightLeftRightLeft, released on 15 May 2009, was to be given away at the remaining concerts of their Viva la Vida tour. It was also released as a free download from their website.

Following the Viva la Vida Tour, Coldplay announced another "Latin America Tour" to take place in February and March 2010, in which they were to visit Mexico, Argentina, Brazil, and Colombia.

In October 2009, Coldplay won Song of the Year for "Viva la Vida" at The American Society of Composers, Authors and Publishers (ASCAP) Awards in London.

Mylo Xyloto (2009 - present)

The band settled on an industrial rock direction and finished recording the new album in mid-2011. When Martin and Champion were interviewed by BBC Radio and asked about the album's lyrical themes, Martin replied "It's about love, addiction, OCD, escape and working for someone you don't like." When asked whether or not their fifth album would be out by the summer, Martin and Champion said that there was plenty of work to be done before releasing it. They confirmed several festival appearances before its release date, especially a headlining spot in the 2011 Rock Werchter, Glastonbury Festival, T in the Park, Austin City Limits Music Festival, Rock in Rio, and Lollapalooza festivals.

In an interview on 13 January 2011, Coldplay mentioned two new songs to be included on their upcoming fifth album, "Princess of China" and "Every Teardrop Is a Waterfall". In a February interview, Parlophone president Miles Leonard told HitQuarters that the band were still in the studio working on the album and he expected the final version would appear "towards the autumn of this year".

On 31 May 2011, Coldplay announced that "Every Teardrop Is a Waterfall" was to be the first single for the fifth album. It was released on 3 June 2011. The band also presented five new songs at festivals during the summer of 2011, "Charlie Brown", "Hurts Like Heaven", "Us Against the World", "Princess of China" and "Major Minus".

On 12 August 2011, Coldplay announced via their official website that Mylo Xyloto is the new album title, and that it will be released on 24 October 2011.

On 12 September 2011, Coldplay released the second single from their upcoming album Mylo Xyloto entitled "Paradise".

On 23 September 2011, tickets for Coldplay's European tour officially went on sale. Demand proved to be very high with most venues selling out in seconds
