ABOUT GREEN DAY

GREEN DAY - vocalist/guitarist Billie Joe Armstrong, bassist Mike
Dirnt, and drummer Tré Cool - were kids from working-class backgrounds who came
of age in the underground punk scene in Berkeley. Even though they had released
two records prior (1039 / Smoothed Out Slappy Hours and Kerplunk), they
announced their arrival with 1994's Dookie, a dynamic blast of exuberant
punk-pop that sold 15 million copies and earned the band its first Grammy® Award
for Best Alternative Music Performance. Over the years, Green Day continued to
top the charts with their subsequent studio albums Insomniac, Nimrod and
Warning, while entertaining millions of fans with their frenetic live shows. But
it was their landmark 2004 album American Idiot that launched Green Day into the
stratosphere. American Idiot debuted at No. 1 on the Billboard chart, spawned
five hit singles, earned seven Grammy® nominations (winning two, including Best
Rock Album), and raised the bar for modern rock and roll. In 2009, Green Day
released 21st Century Breakdown, which won a 2010 Grammy® Award for Best Rock
Album. It spawned two hit singles: the gold "Know Your Enemy," which was the
first song ever to top Billboard's Rock, Alternative, and Mainstream Rock charts
simultaneously, and the double-platinum "21 Guns," which earned them three 2009
MTV Video Music Awards including Best Rock Video. Green Day also took home an
American Music Award for Favorite Alternative Rock Music Artist. Later that
year, Green Day collaborated with Tony Award winning director of Spring
Awakening, Michael Mayer, for the stage musical of American Idiot. The play
bowed at the Berkeley Repertory Theatre in September 2009 and set attendance
records during its limited engagement. The play went on to Broadway and ran for
a year at the St. James Theatre and won two Tony Awards. Their highly
anticipated album Green Day ¡Uno!, the first in a trilogy of new releases, will
bow this fall followed by Green Day ¡Dos! And Green Day  ¡Tré!. For more about
