Green Day is canceling the rest of its 2012 club schedule and postponing the start of its 2013 arena tour.
Bass player Mike Dirnt says Billie Joe Armstrong's "well-being is our main concern" in the band's decision to clear the schedule through Feb 8.
He says in a statement Monday that Armstrong is doing well in his attempt to shake substance abuse problems that emerged publicly in September, when the singer-guitarist had a profane meltdown onstage in Las Vegas.
The Grammy-winning punks also moved up the release date of "Tre," the third installment in a trilogy of albums released over a period of months. The album will be released Dec. 11, more than a month ahead of schedule.
