Music: Green Day - Working Class Heroes

RollingStone on Green Day's origins:

"Massive concussive explosions (rigged by the band's pyrotechnics team) periodically shake the house and unnervingly call to mind the attacks in New York, Madrid, London and Iraq. Four songs into the show, the houselights go out and the arena is plunged into blackness. Armstrong, lit by a satanic red spotlight, pans a hand-held searchlight over the crowd and recites, in menacing tones, the Pledge of Allegiance, while bassist Mike Dirnt pumps out a paranoia-inducing bass line and drummer Tre Cool taps his snare rim like a bomb ticking down to detonation. They explode into 'Holiday' -- an incendiary anti-government song in the tradition of Dylan's 'Masters of War.'"
