Born and raised in Manor Park, East London, she relocated to Nottingham whilst working for a children's charity and initially only considered making music as a way of having fun with friends. However, a chance encounter lead to her earning a place on Future Bubblers - Gilles Peterson's development programme devoted to discovering and nurturing fresh UK talent - and enthused by the experience, Lacey recorded some songs in her living room, then in 2017 self-released her debut EP, 'Black Moon'. The more polished 'When The Sun Dips 90 Degrees' EP followed in 2018, and then 'Morning Matters' EP in 2020 – the EP's title track has clocked up over 14 million plays on Spotify and also saw Yazmin make her COLORS debut performing 'On Your Own'.
