Green Day Staging 'Secret' Benefit Show August 11 in California

Green Day will be performing a special benefit concert Thursday evening (Aug. 11) with all proceeds going to the Cystic Fibrosis Foundation (CFF). According to a post yesterday on the band's website, the group will be playing at The Tiki Bar in Costa Mesa, California, with tickets priced at $20 at the door. And get their early since there are no pre-sale tickets either.

"Be ready to dance!" says a statement from the band while a photo shows the bar with the marquee advertising the charity gig. Snap-happy fans should note that there's a strict no camera and no cell phone policy in effect for the concert, with admission to those 21 years of age and older. Sorry kiddies!

Green Day bassist Mike Dirnt and his wife Brittney also recently attended the Pipeline to a Cure Fundraising event in support of CFF. "The idea is to come here and drop a little bit of coin for a good charity," Dirnt said a YouTube video recorded at the event, adding he previously placed one of his Fender bass guitars on auction to raise funds for the cause.

Green Day have been off the road this year but are reportedly working on their next studio album. The group released 'Awesome As F---,' a live CD/DVD package culled from their 2009-10 world tour in support of their last studio effort, '21st Century Breakdown.'
