This 20-year-old British singer-songwriter got a big boost when she got a MySpace endorsement from Lily Allen. Her first album went on to debut at No. 1 on the U.K. chart after it was released last August. Just now arriving in the U.S., Made of Bricks is built upon the kind of whimsical, quirky pop and Brit-witty lyrics that fans of Allen would no doubt enjoy. On the sprightly highlight, "Foundations," she details the decay of a relationship: "My fingertips are holding on to the cracks in our foundation/ And I know that I should let go, but I can't." No such worries about Nash—she's a keeper.
