As GDA notes, the instrumental seems to be recorded live in the studio—but never mixed. It was apparently in a bonus chapter of the documentary.

¡Cuatro! originally released in September 2013, following Green Day's 2012 trilogy of albums, ¡Uno!, ¡Dos! and ¡Tre!.

It was directed by Tim Wheeler and eventually nominated for the Best Music Film Grammy Award.

Catch Green Day on tour with Against Me! now and Catfish And The Bottlemen this fall.

Here's the instrumental:
