Flood is the third studio album by Brooklyn-based alternative rock duo They Might Be Giants, released in January 1990. Flood was the duo's first album on the major label Elektra Records. It generated three singles: "Birdhouse in Your Soul", "Istanbul ", and the domestic promotional track "Twisting". The album is generally considered to be the band's definitive release, as it is their best-selling and most recognizable album. Despite minimal stylistic and instrumental differences from previous releases, Flood is distinguished by contributions from seasoned producers Clive Langer and Alan Winstanley. John Linnell and John Flansburgh also took advantage of new equipment and recording techniques, including unconventional, home-recorded samples, which were programmed through Casio FZ-1 synthesizers. The album was recorded in New York City at Skyline Studios, which was better equipped than studios the band had worked in previously.

They Might Be Giants, often abbreviated as TMBG, is an American alternative rock band formed in 1982 by John Flansburgh and John Linnell. During TMBG's early years, Flansburgh and Linnell frequently performed as a musical duo, often accompanied by a drum machine. In the early 1990s, TMBG expanded to include a backing band. The duo's current backing band consists of Marty Beller, Dan Miller and Danny Weinkauf. They have been credited as vital in the creation and growth of the prolific DIY music scene in Brooklyn in the mid-1980s.
