Green Day have announced that they're not working on a new album... they're working on three!

The three-piece rock titans will release the three albums over several months:

'¡Uno!' will be out September 25th, '¡Dos!' on November 13th and '¡Tré!' on January 15th 2013.

The albums will follow 2009's huge '21st Century Breakdown'. The band will be working on longtime producer Rob Cavallo in their hometown of Oakland, California.

The band explained:

"We are at the most prolific and creative time in our lives. This is the best music we've ever written, and the songs just keep coming," said the members of Green Day. "Instead of making one album, we are making a three album trilogy. Every song has the power and energy that represents Green Day on all emotional levels. We just can't help ourselves... We are going epic as fuck!"

This summer Green Day play the following worlwide festivals:

18 Tokyo, Japan (Summer Sonic 2012)
19 Osaka, Japan (Summer Sonic 2012)
26 Paris, France (Rock En Seine 2012)
