‘American Idiot’ Cast Calls Grammy Set With Green Day ‘Amazing’

'This is the first time something like this has ever been presented on the Grammy stage,' director Michael Mayer says.

At Sunday night’s Grammy Awards, [artist id="988"]Green Day[/artist] gave fans a taste of what they can expect on the upcoming Broadway run of their “American Idiot” musical , performing their anthem “21 Guns” with the full cast .

But before the Grammy telecast even began, those same cast members were on the red carpet, talking up the finer points of the musical, which first opened in Berkeley, California, last year. And by all accounts, it sounds like it’s going to be a very big show indeed.

“To do a punk-rock opera, there’s something so visceral and exciting about it, and while you get in traditional musical theater, this is something completely different,” Mary Faber, who plays Heather, told MTV News. “A lot of people are comment on how exciting it is to hear female voices singing these songs. It’s really, really exciting.”

Director Michael Mayer — who won a Tony for his work on the Broadway smash “Spring Awakening” — added that the “Idiot” musical (which opens at New York’s St. James Theatre on March 24) is shaping up to be a decidedly ambitious undertaking, one that takes the sprawling saga of Green Day’s hit album and stretches it out on the stage.

“It’s like a rock opera, so we basically staged the whole album, with a few songs from 21st Century Breakdown too,” Mayer said, referring to the band’s latest album, which won the Best Rock Album Grammy on Sunday. “So there’s a story: It’s about a generation of Americans looking for meaning in a post-9/11 world, with the rocking, amazing songs of Green Day. It’s perfect.”

And while the whole cast was excited for the big debut on March 24, they were practically hyperventilating about performing “21 Guns” with the band during the Grammy telecast. After all, they were about to make history.

“This is the first time something like this has ever been presented on the Grammy stage,” Mayer enthused. “It’s unprecedented. And amazing.”
