Frontman Nathan Winneke states: "A Natural Death is about the futility and arrogance of creation and destruction, the overwhelming scale of space and time, and the brutal majesty of nature, the horror of birth, and the beauty of death. Everyone who will ever live will die a natural death, and will soon after be forgotten for eternity. Hopefully this album will serve as a warning to the human race to stop taking itself so seriously, as we have seen the dire consequences of its actions in the future. You are nothing."
Originally the song "Crow Town" was on the album as track 10, and "The Red Tornado" was track 9, this was replaced just after the release with "Broken Trail". In the song "Lif" where various fragments of the previous songs are played throughout, you can hear the crows crowing at one point, exactly as they do in the song "Crow Town" furthermore showing it was an original song for the album.
The song "The Red Tornado" refers to the comic book superhero Red Tornado.
