The Flaming Lips have shared another song from their upcoming album, American Head, which is out September 11 via Warner Brothers. "Mother, Please Don't Be Sad" is a real lighters aloft, swaying stadium album, albeit one which is written from the point of view of a son who has already slipped this mortal coil. Wayne based the lyrics on a real life incident where he was held up and gunpoint while at work, but with an imagined tragic end. It's big, it's kinda weird, it's The Flaming Lips.
