Say Who: Colbie Caillat, 24

Made Waves For: Hit single ‘Bubbly’ on her debut album CoCo. Her new album, Breakthrough included the hummable ‘Fallin’ for you’. Peddled as the next Sara Bareilles, Colbie’s style is reminiscent of Jack Johnson (also her musical hero), and Sarah McLachlan. The track ‘Lucky’ is vocal synergy with duet partner, Jason Mraz. A MySpace artist, her fan base spread through word-of-mouth, which is no surprise with this songwriter-singer’s refreshing and laidback style.
