Two hundred fifty people packed into the Tiki Bar in the Orange County city of Costa Mesa, Calif., on Aug. 11, 2011, paying $20 a head the day before to see one of the world's biggest rock bands after an eight-month hiatus. That audience - along with ones at the Webster Hall Studio in New York; 1-2-3-4 Go! Records in Oakland, Calif.; Mezzanine in San Francisco; and Red 7 in Austin - was unknowingly treated to 20 songs that would appear on Green Day's next three albums.
