Here we have a good handful of GRAMMY-awarded songwriters, producers and other artists adding to Caillat’s beachy singer/songwriter recipe, including Rick Nowels, Greg Wells, John Shanks and Kara DioGuardi (acclaimed songwriter and judge of 2009’s American Idol). But just because there are so many cooks in the kitchen hardly means that Breakthrough isn’t a good album — it’s a great album, albeit somewhat watered down. With continued help from Coco’s collaborators Jason Reeves and Mikal Blue, fans can rest assured that Caillat still coos with that warm Jason Mraz-esque coastal vibe, even in the tunes that muse on broken hearts and complicated relationships like the opening number “I Won’t” and the amorously apprehensive “Begin Again.” The obvious standout “Fallin’ for You” is easily the catchiest tune here with its subtly powerful chorus hooks and persevering themes of summer love.
