The experiences have helped hone her rich, jazz-inflected melodies for a successful solo career.
Testament to her talent, the past 12 months have seen her gain the backing of MistaJam, Zane Lowe, Toddla T, Skream and Benga, and she's been remixed by everyone from Mount Kimbie to Tokimonsta.
Meanwhile, her top 10 hit, Everything You Never Had, with UK producer Breach, further upped the ante.
We were lucky enough to catch her performing live at the official opening of the PRS for Music HQ in Kings Cross a few weeks ago.
Watch her play a stripped back acoustic version of Everything You Never Had below.
