Pyro

Lead singer Caleb Followill explained in a video interview that that this kerosene-crazed track is about a guy who has lost faith in the world in which he lives and he doesn't believe it is as perfect as everyone says. He becomes so disgusted by the world in which he lives that he decides to burn it down: Everything I cherish Is slowly dying, or it's gone

The song is written from the perspective of Sammy Weaver, who was killed in a 1992 firefight with US marshals at Ruby Ridge, Idaho. Sammy's father, Randy Weaver, had a visceral distrust of the US government and refused to appear in court on weapons charges. After a long standoff, the firefight ensued and Sammy, his mother Vicki, and their dog were killed. The story made headlines, and years later, Caleb Followill saw a TV program about the incident, which prompted him to write the song. "There was something about when the son had gotten killed that I was thinking, 'What if he had lived?' I started writing from that mentality.

Pyro is the Latin word for fire and the word Pyromania is used to describe an uncontrollable urge to start a blaze (or a Def Leppard album). Even though the song title is not used in the lyrics the song appears to be about someone with pyromaniac tendencies: Single book of matches Gonna burn what's standing in the way Roaring down the mountain Now they're calling on the fire brigade
