Kaleidoscope Heart

"I've got a thick tongue," sings 30-year-old Sara Bareilles on "Gonna Get Over You," a playfully sexy bit of doo-wop pop. It's the high point on the follow-up to 2007's Little Voice and its megahit, "Love Song." Bareilles veers between fellow pianists Alicia Keys and Regina Spektor, avoiding either's extremes. The result, notwithstanding the title a cappella and an awkward confessional ("Basket Case"), is generic big-box pop; throw a mandolin on the kiss-off "King of Anything" and you have Faith Hill. Which is fine. But there seems to be a more interesting artist lurking in here, somewhere.
