A Weekend in the City is the second studio album by British indie rock band Bloc Party. It was recorded at Grouse Lodge Studios in Westmeath, Ireland, in mid-2006 and was produced by Jacknife Lee. The album was refined and mixed at several locations in London at the end of 2006. It was released on 24 January 2007 in Japan and in the first week of February in the rest of the world, with Wichita Recordings as the primary label. The album peaked at number two on the UK Albums Chart and on the Irish Albums Chart. In the United States, it entered the Billboard 200 at number 12.

Bloc Party worked to craft an album that distanced them from the conventional guitar band set-up by incorporating more electronically processed beats and additional instrumentation. Computer programs were extensively used to enrich and amend recorded takes, while a string sextet was hired to perform on some of the tracks. The subject matter of frontman and chief lyricist Kele Okereke's lyrics for A Weekend in the City covers issues such as drug use, sexuality, and the media's use of moral panic surrounding issues such as terrorism. The album's three original singles, "The Prayer", "I Still Remember", and "Hunting for Witches", address these themes respectively.

Bloc Party's new musical directions and more forthright lyrics either impressed or alienated critics. Reviewers generally treated A Weekend in the City as an important stepping stone for the band members in their quest for musical maturity, while The Guardian included it in its list of the "1000 Albums To Hear Before You Die". In November 2007, the album was re-released globally—with the final single, "Flux", as a bonus track—to coincide with Bloc Party's extensive touring schedule.

All band members of Bloc Party conceived A Weekend in the City during 2005 while on tour in support of their critically acclaimed debut album Silent Alarm. Despite missing their home city of London, the quartet became increasingly disillusioned with the culture in the area each time they sporadically returned. Band member Gordon Moakes has noted, "The contrast we saw between being away on tour and being home ... we would see that London wasn't changing really and that the people we'd grown up with were part of that." Okereke wrote many songs in 2005 and early 2006 and used a concept he called "Urbanite Relaxation" to expand upon the themes of life and leisure in the metropolis. The band recorded around 30 soundchecks for the initial lyrics using a MiniDisc player. The rest of the tracks were written in April 2006 before they entered the studio recording process.

The band members drew up a shortlist of possible producers in early 2006, which included dance music-oriented staff such as Chemical Brothers sound engineer Steve Dub and high-profile producers like Garret "Jacknife" Lee. At the time, Moakes told Rolling Stone that the album would hopefully include electronic, processed beats and a sound in the vein of alternative rock band Radiohead and indie rock ensemble TV on the Radio. Bloc Party wanted to expand their sonic palette without losing the musical "jerkiness" of Silent Alarm. They selected Lee—who had worked with world-renowned act U2 and indie rock band Snow Patrol—based on the rapport that developed between the two parties while recording the demo song "I Still Remember", which later appeared in A Weekend in the City.

Moakes has explained the choice of producer by stating that the band members were looking to work with someone who could help them craft an accomplished album, "although as much as anything it's about finding someone who you'd want to spend six weeks in an enclosed space with". Before the studio sessions, Bloc Party listened to varied musical sources, from composers Philip Glass, György Ligeti, and Krzysztof Penderecki to urban artists Amerie and Missy Elliott. The band members were largely disillusioned with the evolution of contemporary guitar music and aimed to re-create the highly stylised production values of R&B and hip-hop records, while relying on an atmosphere similar to neo-classical music.

In mid-2006, Bloc Party travelled to Lee's Grouse Lodge Studios in Westmeath, Ireland, to record A Weekend in the City. The band members initially worked by experimenting with their respective instruments and sound check arrangements. Moakes additionally focused on using different types of synthesiser. All parties soon moved to the main recording room, a large area with "a lot of natural ambience" according to sound engineer Tom McFall. A makeshift booth was built around the back of the drum kit to reduce any sonic interference, while a roof was sometimes used over drummer Matt Tong to isolate a pure sound. Different types of microphones were used for each component of the drum kit. The miking scheme was crucial to prepare the drum tracks for the looping and processing Lee planned using production program Logic.

The band worked by setting up all the instruments with only a single power amplifier. McFall has pointed out that distorted and heavily compressed mics were used to capture some of the room's ambience "to add a bit of grit" to the instrumental tracks; the recordings were often processed further using distressors, special types of compressor noted for their distinctively aggressive sound. The production staff tried other unconventional effects once the basic tracks were recorded. The band sometimes performed while Tong's kit was re-amped and played sections live while a brick was placed on the sustain pedal of a piano to capture the vibrations during the performances. During the six weeks at Grouse Lodge, Bloc Party tried multiple versions of songs and, at times, attempted playing live alongside recorded versions of the same track.
