Blink-182 returned to Jimmy Kimmel Live last night to play "Up All Night," a heavy, surprisingly mature number from their new album, Neighborhoods. Though the song is a duet between Tom DeLonge and Mark Hoppus, DeLonge says it's pretty close to sounding like something by his other band. "If you listen to 'Up All Night' it sounds like Angels and Airwaves," he told Rolling Stone. "I mean, that's who I am. Angels and Airwaves is a complete, pure reflection of who I am."
