The incident when Eric Church adjusted the brightness of his bathroom light to help his son go to sleep came back to him after the 2017 Vegas shooting
. Right after the tragedy, Church had a songwriting session lined up with Jeff Hyde; they started talking about how everybody needs more light in the same way that Boone did. Inspired they rapidly penned "Monsters."
"It will always be a song that I think about where I was at that time in my life, where my kids were, and how just that little bit of light, is what made the difference," explained Church. "That's the key, that's where the second verse goes to and the overall theme of monsters is it's just that much, you know? It's not 'this much.' It's not a big blinding light. It's this much light that made the difference and that little nugget is what I carry with me on that."
