Green Day has released the trailer for their documentary called ¡Cuatro!, which follows the making of their albums Uno!, Dos! and Tre!. The film will be screened for the first time this weekend at the X Games in Aspen, Colorado. The screening will also be the first public appearance by Billie Joe Armstrong since his stint in rehab.

In the trailer, you see that the band is a little bit nervous about bringing someone in to document their process, especially since they didn’t have all of the details hammered out. It’s the first time in twenty years that they’ve allowed access like this.

In a statement, Mike Dirnt said:

Over the last year while we were recording our trilogy, we posted multiple clips every week so fans can see parts of the recording process of Uno! Dos! Tre! . . . Cuatro! brings our fans one step closer by giving them even more access and revealing what it was like for us to make these records.

There’s no word on an official release date for the film.
