For the first time in nearly five years, the band appeared on stage together as presenters at the February 2009 Grammy Awards, and announced their reunion. The trio embarked on a reunion tour of North America from July to October 2009, with a European trek following from August to September 2010. Barker, suffering from a fear of flying after his accident, traveled via bus domestically and by an ocean liner for overseas dates. The recording process for "Neighborhoods", the band's sixth studio album, was stalled by its studio autonomy, tours, managers, and personal projects. DeLonge recorded at his studio in San Diego while Hoppus and Barker recorded in Los Angeles—an extension of their strained communication. The self-produced album—their first without Jerry Finn since "Enema of the State"—was released in September 2011 and peaked at number two on the "Billboard" 200. Its singles—"Up All Night" and "After Midnight"—only attracted modest chart success, and label Interscope was reportedly disappointed with album sales.
