The teaser trailer for forthcoming animated feature Sing made its appearance during yesterday's broadcast of the Grammy Awards. Written and directed by Garth Jennings for Universal/Illumination studios, the film will feature an original score by Joby alongside myriad pop songs as the animal contestants of a singing contest battle it out for the grand prize. Joby has previously worked with Jennings on feature films The Hitchhiker's Guide to the Galaxy (2005) and Son of Rambow (2007). Sing is due for release at the end of this year — watch the trailer below!
