On September 24, Green Day's Billie Joe Armstrong checked himself into rehab after an onstage rant at the iHeartRadio Festival in Las Vegas. At the time, the band announced, "We regretfully must postpone some of our upcoming promotional appearances." Unfortunately, today it was announced that Green Day's appearance at this year's Voodoo Experience is among those cancelled events.

According to this afternoon's press release:

"Canceling shows is something we rarely do," said Tré Cool.  "We never want to let our fans down, and we are grateful for all of you being understanding during this time." 

According to Loudwire.com:

In an interview with BBC Radio 1 [via NME], Mike Dirnt revealed that the decision to send Armstrong to rehab wasn’t a difficult one, “We had to put the life of our friend in front of everything,” says Dirnt. There were also “signs of things hitting the fan” adding, “we hadn’t slept in forever.”

Dirnt continues, “Hindsight is 20/20… it was a tremendous undertaking… It catches up with you a little bit. We definitely jumped off a moving train.” As for the future of Green Day’s musical career, Durst says, “We’re still getting ready for the next phase.”

Voodoo organizers plan to have a comment in the morning.
