Some of the material from
Britpop was teased in mixes before the album's release, such as tracks "Soulbreaker" and "Equine". The early stages of the album's design began in 2020, when Cook lived in Montana with his partner
Alaska Reid during
COVID-19 lockdowns. Cook said, "I was the only British person there and having that sense of being a bit of an alien... So a way of digging into what an A. G. Cook album could be was to use this as a strange launching pad, finding this thing that's slightly too loaded." Cook released "Silver Thread Golden Needle" 1 January 2024. The song was previously premiered in 2021 at
Eckhaus Latta's Spring 2022 New York showcase.
Britpop was announced alongside the release of the title track on 23 February. Cook announced the Britpop Roadshow: a series of mini residencies in Los Angeles, London and New York City across April and May to promote the album. He additionally teased the track list on TikTok in late March. Cook also launched the sites
Witchfork,
Wandcamp, and
Wheatport as an alternate reality project that parodied
Pitchfork,
Bandcamp, and
Beatport. These sites were made inactive after a few weeks of regular posts. "Soulbreaker" was released as a single on 17 April, alongside an animated music video directed by Gustaf Holtenäs. == Music and lyrics ==
