There has been a lot of attention given to the so-called neo-soul sound, most of it focused on male artists. So how come the folks making the best records are women? One spin of ex-Vertical Hold leader Angie Stone's solo debut and it is clear you are listening to a grown-up woman, not some kid with stars in her eyes who is dictated to by a producer or three. No, the deeply felt grooves and offhand sexiness that make Black Diamond sparkle are things that can only come when you've lived a little. Like Macy Gray's On How Life Is and N'dea Davenport's (criminally ignored) self-titled disc, this is the wondrous sound a woman makes when she's free to create her own music but smart enough to keep the status quo satisfied. On tracks like the smoky "Green Grass Vapors" and "Everyday", Stone, with her rich Gladys Knight-like voice and finger-popping élan, conjures up soul's past without making herself a prisoner of it. Not surprisingly for this key collaborator on D'Angelo's Brown Sugar, Stone kicks a laid-back, fluid vibe, but her clear tone and off-kilter way with a melody make you sit up and pay attention. --Amy Linden
