Though "Red Sector A," like much of the album from which it comes, is set in a bleak, apocalyptic future, what Lee calls "the psychology" of the song comes directly from a story his mother told him about the day she was liberated.

"I once asked my mother her first thoughts upon being liberated," Lee says during a phone conversation. "She didn't believe [liberation] was possible. She didn't believe that if there was a society outside the camp how they could allow this to exist, so she believed society was done in."
