Machine Head frontman Rob Flynn told Kerrang! that he wrote three entirely different versions of this song. "I wrote one about the Newtown (school) shooting. That really affected me, that whole story. But they were scrapped. Then I wrote another about something else – and that didn't make it on the record. So the song is about the (Charles) Manson murders. I had read a lot of books on this whole thing when I was my 20s, and I'd watched all the movies, so I knew the subject well. It's obviously horrific and tragic: but it's also fascinating. He wasn't even a man who did these murders– he got other people to do them."
"I remember speaking to (drummer) Dave (Maclean), and he'd just seen a new documentary about it," he continued. "So I just started writing the lyrics."
"Of the three (lyric versions) I'd written, I didn't necessarily think this was the right one for the song," Flynn added. "But when I heard them back with the music, I knew it was working."
