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. ~ Stephen Thomas Erlewine, All Music Guide
Sweetness rules on Colbie Caillat's debut, Coco, which is perhaps only appropriate for an album bearing that name. The record doesn't play like a toasty mug of chocolate on a winter's day, though; it's a sugary lemonade on a breezy summer afternoon. It's light and comforting, a familiar blend of sunny pop and singer/songwriter tropes that flirt with cliché but never sound hackneyed -- a lighter, brighter spin on Norah Jones that sounds like an ideal soundtrack to a few hours in a cozy coffeehouse or a montage on Grey's Anatomy, whatever comes first. If that gives the impression that Caillat is a little calculated -- and if her music-biz heritage (her dad co-produced Fleetwood Mac's Rumours and Tusk) gives the sense that she may have had a silver spoon, and if her celebrated MySpace popularity is also initially suspect -- then as an album Coco shows no crassness or coldness: it flows easily and, yes, sweetly, filled with gently ingratiating melodies and delivered with warmth and a casual charisma that proves to be quite endearing by the end of the record. Caillat doesn't attempt anything approaching a major statement -- the album is filled with songs about love and life -- but that's her appeal: she sings about simple, everyday things in an unassuming manner, letting her melodies and girl-next-door charm carry the day, and they do so winningly on this nicely mellow debut. ~ Stephen Thomas Erlewine, All Music Guide
