Isabelle Brown may still be just 15 years old, but she's already proving herself to be a prodigious talent. Her debut EP, 03, dropped today and her debut show in London, taking place tonight at Kansas Smitty's, sold out immediately. On top of all of that, she's also premiering the video for EP extract "What U Waiting 4", a classic-sounding R&B track steeped in influences like Nina Simone and the jazzier end of the hip-hop spectrum. 

Produced and directed by LiteSwitch TV, Dani Sawyerr and Isabelle Brown herself, the video follows Brown and her friends in their school uniform as she lays her rich and powerful voice over the golden, jazzy instrumental. If you're struggling to make it through to the weekend, put this one on loud for the ideal wintry pick-me-up.
