Eight years since Blink-182 released their last album, the pop-punkers are back with their first new song, "Up All Night," the lead single from their fall LP.  Frontman Mark Hoppus has said the band are expanding beyond their radio friendly punk sound for the album, and "Up All Night" kicks off with some experimental (well, for Blink-182) guitar riffage and a quasi-ska drum beat. The lyrics are fairly dark, too: Hoppus and DeLonge confess about the "demons that keep [them] up all night." Blink-182 are hitting the road for a 40-date summer tour with My Chemical Romance, beginning August 5 in Holmdel, NJ, and ending October 15 in San Diego.
