On 29 January 2020, the band announced its new project, "Song Machine". Eschewing the typical album format of releasing music, Song Machine is instead a web series that sees the band releasing one new song a month as "episodes" to the series, with 11 episodes releasing to comprise the first "season." Elaborating on the idea behind "Song Machine" in a radio interview shortly after the announcement of the project, Albarn explained that "We no longer kind of see ourselves as constrained to making albums. We can now make episodes and seasons." Each episode features previously unannounced guest musicians on new Gorillaz material, with the first being "Momentary Bliss", which was released on 31 January and features both British rapper Slowthai and the Kent-based punk rock duo Slaves.
