Bummed is the second studio album by English rock band Happy Mondays, released on 21 November 1988 on Factory Records. During 1987 and early 1988, the band discovered house music and the rave drug ecstasy. Factory producer Martin Hannett was subsequently enlisted to produce the band's next album. Sessions were held at The Slaughterhouse recording studio in Driffield over three weeks. Hannett moved recording to Strawberry Studios, where extra instrumentation was added. Bummed is a Madchester-style psychedelic funk album, where much of the lyrical content was influenced by the 1970 film Performance, with dialogue from the film sampled throughout.

Happy Mondays toured the United Kingdom supporting James in late 1988, which coincided with the release of the lead single from Bummed, "Wrote for Luck", on 31 October 1988. Happy Mondays played a series of headlining shows to close out the year; stints in mainland Europe and the UK followed in the first half of 1989. "Lazyitis – One Armed Boxer", an alternative version of the closing track "Lazy Itis", was released as the second single from the album on 6 May 1989. Following this, the band embarked on a North American tour, supporting labelmates Pixies. At the suggestion of their manager, remixes of "Wrote for Luck" – retitled "W.F.L." – were made by Paul Oakenfold and Vince Clarke of Erasure. These versions were released together as part of a reissued "W.F.L." single in September 1989.

Bummed received generally positive reviews from music critics, many of whom praised Hannett's production work. It peaked at number 59 on the UK Albums Chart, though it was initially seen as a disappointing seller by Factory Records. The original version of "Wrote for Luck" reached number seven on the UK Independent Singles Chart. "Lazyitis – One Armed Boxer" charted at number 46 on the UK Singles Chart, followed by the remixed "W.F.L." at number 68. Bummed appeared on album of the year and best of decade lists by NME, Sounds, and Q. "Wrote for Luck" and Bummed have been viewed as defining releases of the acid house era and the Second Summer of Love.

Happy Mondays released their debut studio album, Squirrel and G-Man Twenty Four Hour Party People Plastic Face Carnt Smile (White Out), in April 1987 through Factory Records. The album had to be reissued due to the track "Desmond" sharing the same melody with "Ob-La-Di, Ob-La-Da" (1968) by the Beatles. They were threatened with legal action over this; it was replaced on subsequent copies with the hastily recorded "24 Hour Party People". During the session for it, the band also worked on several new tracks for their next album. The lead single from Squirrel and G-Man Twenty Four Hour Party People Plastic Face Carnt Smile (White Out), "Tart Tart", earned Happy Mondays national exposure for the first time when its music video was played on Channel 4's The Chart Show.

In the first half of 1987 (between recording and the release of their debut), Factory A&R member and DJ Mike Pickering was introducing house music at the label's Haçienda club. The members of Happy Mondays would visit the venue to immerse themselves in Pickering's selections. It would prove to have an influence on the members, as it served as a bridge between the music they heard in their heads and what they wrote. The band at this point did not fit into any particular music scene; grebo was establishing itself, a new wave of gothic rock was being ushered in, and American indie bands were rising to prominence. In October 1987, the band embarked on their first headlining tour of the United Kingdom, which saw the debut of new songs "Fat Lady Wrestlers" and "Moving in With".

Shortly before Christmas 1987, Happy Mondays dancer Bez was introduced to the rave drug ecstasy and quickly introduced it to the other members. Frontman Shaun Ryder grew tired of their manager, Phil Saxe, wanting someone who was more in tune with the scene at the Haçienda. In early 1988, Saxe left his role, citing that he could not devote enough time to it. He was replaced by Nathan McGough, who took on the role full-time at his suggestion. McGough had been a member of Factory band The Royal Family and the Poor and previously managed Factory act Kalima. McGough's first measure was getting the band legally signed to Factory, who had no formal contracts with their artists up to that point. Around this time, the members had a lucrative business selling ecstasy; through various people, they had accumulated 15,000 pills of the drug.

McGough organised Happy Mondays to record demos of their new material at Out of the Blue Studios in Ancoats. Factory became aware that the band were known around London as being a difficult act to record with, not helped by the poor reception to the production of their debut album. Ryder was impressed with the self-produced material at Out of the Blue and asked if they could self-produce their next album, only to be told that they needed a known, popular producer. Factory director Alan Erasmus suggested Martin Hannett; he worked with the label in their early years and split following the construction of the Haçienda, which he was opposed to.

McGough liked the idea of having Hannett, as did Ryder, who learned of him through New Order frontman Bernard Sumner and his work on Unknown Pleasures (1979) by Joy Division. Factory Records co-founder Tony Wilson was hesitant about the idea before realising it would work well for both Hannett and the band. Hannett had been struggling financially at the time, stemming from a prior lawsuit with Factory. Bassist Paul Ryder and drummer Gary Whelan drove to pick Hannett up from Chorlton to take him to the studio. Happy Mondays and Hannett decamped to Strawberry Studios in Stockport with the intent to record demos; however, Hannett and the members instead spent session time in separate pubs. They ended up only recording an early version of "Wrote for Luck".
