Despite its title, What to Say does not find Daphne Willis at a loss for words. The 22-year-old singer/songwriter revels in long, flowing lyric lines on her debut album, singing them with the air of a jazz-enraptured beat chick. With her bopping sense of rhythm, Willis brings the likes of Rickie Lee Jones and Edie Brickell to mind, though Jason Mraz is also a useful reference point. The playful vocal flights in “Not Always Easy,” “Far Away” and “Love and Hate” glide over lightly funky guitars and slippery grooves. She does best on uncluttered tracks like the seductive “Yellow Dress” and the warm ‘n’ mellow “Still Tryin’.” Willis takes a decent shot at a mainstream pop single with the tropical-tinged “Bluff.” The most affecting song is “Jim Thornton,” a wistful meditation on mortality inspired by the passing of her grandfather. Willis’ songs are alive with motion — fittingly, she seems very much in transit herself. When it clicks, What to Say has a dizzy, high-flying sparkle to it, carried along by Willis’ word-drunk enthusiasm.
