Green Day has not one but two documentaries that will premiere at the South By Southwest music and film festival in Austin. One is Cuatro!, which follows the group as they made their last three albums, Uno!, Dos!, and Tre! The other is Broadway Idiot, which follows Billie Joe Armstrong’s journey to Broadway for the stage version of the punk opera, American Idiot.

As of this posting, the SXSW Web site doesn’t have a date for when the two features will be shown, though that information should be nailed down in the next couple of weeks.

If you’re looking for a great festival to attend, start making your plans now because hotels in Austin fill up quick!
