Green Day - 21st Century Breakdown

21st Century Breakdown is the eighth studio album by the American punk rock band Green Day. It is the band's second rock opera, following American Idiot, and their first album to be produced by Butch Vig. Green Day commenced work on the record in January 2006. Forty-five songs were written by singer and guitarist Billie Joe Armstrong by October 2007, but the band members did not enter studio work with Vig until January 2008. The writing and recording process spanned three years and four California recording studios and was finished in April 2009.
