Bad news for Green Day fans: the band has canceled Friday's free "secret" show in Burbank, CA.  On Wednesday, Green Day announced that the upcoming gig was called off because city officials denied the band the necessary permits for the concert, citing concerns for the safety of the potentially large number of concert-goers.

Green Day’s next scheduled performance is at Japan's Summer Sonic Festival on August 18.  They'll return to the U.S. to headline the the annual Voodoo Music Experience in New Orleans, which runs October 26-28.
