The British singer is a natural, bringing a deeply jazzy sensibility to songs that would sit comfortably beside those of Erykah Badu and Jill Scott. There's an audible effervescence here, no matter which genre she touches—whether it's UK garage, deep house or retro-leaning popcorn soul—and a kind of irrepressible hopefulness. But more than that, listening to this woman sing just makes you feel good.
