At first, Costa's debut is deceptively simple turn-of-the-millennium R&B. Yet there are interesting embellishments throughout: "So Have I for You" collapses into a drum 'n' bass break, and the sludgy rhythm of "Tug of War" surrenders to its noisy bridge. Her voice, when not processed to the point of anonymity, is rugged and bluesy. Not a revelation, but an odd detour.
