We are so glad to hear this!
Green Day have been away for FOUR YEARS, except for last year's Christmas single, but now they're back not just with a hot new song — but with an entire album!
Bang Bang (not a Jessie J cover) addresses the problem with gun violence in the U.S. with the rockers' typical pop punk energy and cleverness.
And if the rest of Revolution Radio, out October 7, is anything like this we are SO ready!
See the lyric video for Bang Bang (below)!
