Five years in the making, Kerli's 2013 EP, Utopia, sees the Estonian singer/songwriter transform from icy goth rocker to empowering dance-pop darling. "Put your hearts up," she coolly commands over skittery beats and booming bass drops on "Can't Control the Kids," before she soulfully bellows on the triumphant house anthem "The Lucky Ones" and suggestively moans like Britney on slithery electro-pop groover "Sugar." Meanwhile, slick piano ballads "Love Me or Leave Me" and "Chemical" capture the moody elegance of Kerli's earlier ambitions.
