Baby Blue is an English rapper and singer (born Rachel Johnson in London). She is known for her work with singer Estelle and collaborations with John Legend, Madness, Sway, Shystie, Ms. Dynamite and Lady Sovereign. Baby Blue has a sound that fuses Hip-hop with Grime, R&B and Soul. Baby Blue started rapping while at school and eventually recorded a track called 'I Woulda', which was inspired by her cousin's gang-related death in the US. The track received heavy rotation and was the start of Baby Blue's career as a recording artist. When she was 19 she sent her music to UK artist Estelle, who immediately invited Baby Blue to New York to record the song 'Hey Girl' featuring John Legend, as well as 'Don't Talk', another track for Estelle's dÃ©but album The 18th Day, which was certified gold in the UK and she was also featured rapping in the video for the hit top 20 track 1980. Later that year, Blue released the mixtape 'Out of the Blue Vol I' (with Volume II released two years later) which featured Estelle, members of So Solid Crew, Shystie, Sway, and Akala. Her first solo music video was for the single 'Sometimes,' which was released to push Vol II of the mixtape. This led Mobo Magazine to dub her "The Uncrowned Queen of the UK" and MTV to list her as "one of the hottest up 'n' coming stars".
