Contributed by swank, Posted by Green Day

With the first of their three album trilogy set for release on September 25th, 2012, Green Day have begun the slow trickle of hype-building leading up to the in-store dates. Titled ¡Uno!, the album will be followed by ¡Dos! on November 13th, 2012 and ¡Tré! on January 15th, 2013.

The band has posted the artwork along with a trailer featuring a some of instrumental music which presumably appears on the music. Speaking of presuming, the first album cover has vocalist/guitarist Billie Joe Armstrong so we're wildly speculating that ¡Dos! will feature bassist Mike Dirnt and ¡Tré! will feature Tré Cool.
