Stunning chanteuse Tiffany Alvord has quite a fan following due to her gorgeous covers of Selena Gomez and OneRepublic (her interpretation of Katy Perry's 'The One That Got Away' is a particular home run), but her luminous piano version of Bieber's 'Pray' is one of her finest covers. High production values and her sweet, soulful voice give the song new life in Alvord's capable hands.
