On the face of it, the self-titled debut from 15-year-old Birdy doesn't seem any different from the hastily assembled albums released by various X Factor alumni. But dig a little deeper and you'll find that this stripped-back collection of lesser-known hits and album tracks reads like a who's who of lo-fi hipster indie rock. As clever and subtle as these reworkings are, it's Birdy's youthful and fragile voice that steals the show, whether it's replicating the multi-layered harmonies of Fleet Foxes' "White Winter Hymnal," providing a poignancy to Bon Iver's "Skinny Love," or showcasing her scale-gliding abilities on the Postal Service's "The District Sleeps Alone Tonight." Thanks to her haunting tones and a compelling production, Birdy impressively avoids being the try-hard affair you'd expect.
