After a few months of waiting for official word, we finally have an actual release date for ¡Cuatro!, which is now set to be released April 9th. Emails were sent to those who pre-ordered the trilogy box-set saying they would be getting their copy around this date. It's still not clear if (or when) the documentary will be available to purchase on its own.
The making-of documentary followed Green Day into the studio as they prepared and recorded their trilogy ¡Uno!, ¡Dos!, ¡Tre!.
An edited hour-long version of the documentary was aired back in November on Vh1. The full film made it's debut earlier this year at the Winter X-Games in Aspen, CO, followed by a Q&A with Mike and Tre. More recently it was screened at SXSW in Austin, TX.
