Though it's been in the works - and premiered in 2012 - and was originally set for release last month, Warner Music Group is now announcing a September 24, 2013 release date for ¡Cuatro!.

The film promises to pull back the curtain and takes fans inside the world of Green Day, from the various spontaneous live performances in select cities across the U.S. to the chronicling of their creative process while conceptualizing and recording their current trilogy of albums: ¡Uno! , ¡Dos! and ¡Tré!.
