Blur are an English rock band formed in London in 1988, consisting of singer Damon Albarn, guitarist Graham Coxon, bassist Alex James, and drummer Dave Rowntree. Their debut album, Leisure (1991), incorporated the sounds of Madchester and shoegaze. Following a stylistic change influenced by British guitar pop groups such as the Kinks, the Beatles, and XTC, Blur released the albums Modern Life Is Rubbish (1993), Parklife (1994), and The Great Escape (1995). Parklife lead single "Girls & Boys" (1994) became a hit in the UK and the US, respectively peaking at number 5 on the UK singles chart and number 59 on the Billboard Hot 100. As a result, the band helped to popularise the Britpop genre and achieved mass popularity in the UK, aided by a widely publicised chart battle with rival band Oasis in 1995 dubbed "the Battle of Britpop".

Blur's self-titled fifth album (1997) saw another stylistic shift, influenced by the lo-fi styles of American indie rock groups, and became their third UK chart-topping album. It's single "Song 2" became popular on alternative radio in the US. Their next album, 13 (1999), saw the band experimenting with electronic and art rock styles, and featured more personal lyrics from Albarn and Coxon. Their seventh album, Think Tank (2003), continued their experimentation with electronic sounds and was shaped by Albarn's growing interest in world music, featuring more minimal guitar work. Coxon left the band early in the sessions for Think Tank, and Blur disbanded for several years after the album's tour in 2003.

In 2009, Blur reunited with Coxon and embarked on a European reunion tour. In the following years, they released several singles and compilations and toured internationally. In 2012, they received the Brit Award for Outstanding Contribution to Music. Their eighth album, The Magic Whip (2015), was their first in twelve years and the sixth consecutive Blur studio album to top the British charts. After the Magic Whip tour, Blur went on hiatus until the release of their ninth album, The Ballad of Darren, in 2023.

Blur were formed in December 1988 when bassist Alex James joined Damon Albarn's band, Circus, and they changed the name to Seymour after J. D. Salinger's Seymour: An Introduction. Already in the band were drummer Dave Rowntree, who had joined in October, and guitarist Graham Coxon, Albarn's childhood friend from Essex, who was studying at the University of London's Goldsmiths College along with Albarn and James. The group performed live for the first time in summer 1989 in the goods shed of the East Anglian Railway Museum at Chappel & Wakes Colne. In November, Food Records' A&R representative Andy Ross attended a Seymour performance that convinced him to court the group for his label. After this he brought label founder David Balfe to a couple more, including a particularly packed gig at The Falcon, Camden. The only concern held by Ross and Food was that they disliked the band's name. Food drew up a list of alternatives, from which the group decided on Blur. Food Records finally signed the rechristened band in March 1990.

From March to July 1990, Blur toured Britain, opening for the Cramps, and testing out new songs. In October 1990, after their tour was over, Blur released the single "She's So High", which reached number 48 in the UK singles chart. The band had trouble creating a follow-up single, but they made progress when paired with producer Stephen Street. The resulting single release, "There's No Other Way", became a hit, peaking at number eight. As a result of the single's success, Blur became pop stars and were accepted into a clique of bands who frequented the Syndrome club in London dubbed "The Scene That Celebrates Itself". NME magazine wrote in 1991, "[Blur] are [the] acceptable pretty face of a whole clump of bands that have emerged since the whole Manchester thing started to run out of steam."

The band's third single, "Bang", performed relatively disappointingly, reaching only number 24. Andy Ross and Food owner David Balfe were convinced Blur's best course of action was to continue drawing influence from the Madchester genre. Blur attempted to expand their musical sound, but the recording of the group's debut album was hindered by Albarn having to write his lyrics in the studio. Although the resulting album Leisure (1991) peaked at number seven on the UK Albums Chart, it received mixed reviews, and according to journalist John Harris, "could not shake off the odour of anti-climax".

After discovering they were £60,000 in debt, Blur toured the United States in 1992 in an attempt to recoup their financial losses. The group released the single "Popscene" to coincide with the start of the tour. Featuring "a rush of punk guitars, '60s pop hooks, blaring British horns, controlled fury, and postmodern humor", "Popscene" was a turning point for the band musically. However, upon its release it only charted at number 32. "We felt 'Popscene' was a big departure; a very, very English record", Albarn told the NME in 1993, "But that annoyed a lot of people ... We put ourselves out on a limb to pursue this English ideal and no-one was interested." As a result of the single's lacklustre performance, plans to release a single named "Never Clever" were scrapped and work on Blur's second album was pushed back.

During the two-month American tour, the band became increasingly unhappy, often venting frustrations on each other, leading to several physical confrontations. The band members were homesick; Albarn said, "I just started to miss really simple things ... I missed everything about England so I started writing songs which created an English atmosphere." Upon the group's return to Britain, Blur (Albarn in particular) were upset by the success rival group Suede had achieved while they were gone. After a poor performance at a 1992 gig that featured a well-received set by Suede on the same bill, Blur were in danger of being dropped by Food. By that time, Blur had undergone an ideological and image shift intended to celebrate their British heritage in contrast to the popularity of American grunge bands such as Nirvana. Although sceptical of Albarn's new manifesto for Blur, Balfe gave assent for the band's choice of Andy Partridge (of XTC) to produce their follow-up to Leisure. The sessions with Partridge proved unsatisfactory, but a chance reunion with Stephen Street resulted in him returning to produce the group.
