Julie Dexter might be the best soul singer you haven't heard about -- and if you have, make sure you have a ticket to her upcoming gig at Club 75. The Atlanta-based jazz-funk-soul chanteuse draws favorable comparisons to Alicia Keys (and deserves them), but with less gloss (that's a good thing). The Jamaican-born singer-songwriter arranges, composes, produces, and sings like she's spent the day listening to Billie Holiday and Sade.
