Colbie Caillait's breakthrough arrived before Breakthrough, when her debut Coco turned into a breezy surprise hit. Breakthrough isn't meant to catapult Caillait into a mainstream that already knows her, but to consolidate her success, so it emphasizes the studio recording ever so slightly over songs. Breakthrough winds up being a bit slicker and sleeker than Coco, but not quite at the expense of Caillait's charms. Underneath the smooth gloss, Caillait remains the girl next door singing songs of love as light, crisp, and addictive as a sugar cookie. (A 17-track deluxe edition was also released.) ~ Stephen Thomas Erlewine, Rovi
