The origins of The Lost Tapes date back to 2011. Having parted ways with previous configurations of the Sugababes across the 2000s, the original founding trio, Mutya Buena, Keisha Buchanan, and Siobhán Donaghy, reconvened to write new material. Because the corporate brand name remained tied to an alternative lineup managed by Crown Music, the women performed and recorded under the banner Mutya Keisha Siobhan (MKS).
Working in London and Los Angeles alongside high-profile producers like Devonté Hynes (Blood Orange), Richard "Biff" Stannard, MNEK, and Cameron McVey, the trio laid down dozens of tracks. Polydor released their critically adored comeback single "Flatline" in August 2013, which peaked modestly at number 50 on the UK Singles Chart due to minimal promotion. Internal friction with the label followed, and plans for the full-length record stalled indefinitely.
Between 2014 and 2019, unfinished bounces and studio stems migrated into public forums. Rough MP3 demos of "Boys," "Love in Stereo," and "Today" populated rip blogs, commonly indexed under forum tags like "MKS/MVT Tapes" or "Unreleased Sugababes 4.0." Rather than allowing those bootlegs to define their legacy, the trio secured the official Sugababes trademark in 2019. By Christmas Eve 2022, they released the material independently through their own imprint, distributing the remastered leaks directly to global consumers.
