Don't let Leslie Grace's powder puff of a voice fool you: This bachata up-and-comer's debut is a revolution. Or at least the first half is. Disregard the by-the-numbers, Pitbull-ish dance-pop at the end. Instead, focus on Grace's ability to interweave Spanish and English, bachata and R&B into a seamless, sing-along-able tapestry on tracks like "No Me Arrepiento." Delight in the elegant, surprising lineage she draws between classic girl groups and bachata on her rehabbed vintage tracks. And especially, revel in the power with which this young woman wields this boy-dominated genre.
