The album's cover art is a homage to Johnny Craig's cover art from issue #35 of the comic book The Vault of Horror.  The artwork was created by German artist Florian Bertmer.  Agoraphobic Nosebleed's side is a departure from their usual micro-burst grind style.  It features two distorted basses, no guitars, slower tempos, longer running times and constant shifts in tempo and time signature.  Apartment 213's Steve Makita performs vocals on every track, along with those of ANb vocalist Jay Randall.  The overall sound is similar to that of powerviolence pioneers/legends Man Is the Bastard.  Apartment 213's side is mostly re-recorded versions of previously released songs, dating as far back as their first 7" from the early 1990s.

The Bomb (film): The Bomb is a 2015 American documentary film about the history of nuclear weapons, from theoretical scientific considerations at the very beginning, to their first use on August 6, 1945, to their global political implications in the present-day.  The two-hour PBS film was written and directed by Rushmore DeNooyer, who noted the project took a year and a half to complete, since much of the film footage and images was only recently declassified by the United States Department of Defense.  According to DeNooyer, “It wouldn’t take very many bombs to really change life on Earth, ... The idea that there are thousands of them sitting around is pretty scary.  I don’t think people today realize that.  They don’t think about it.  I don’t think they are scared.  But in a way, they should be.”  Mark Dawidziak, of the "Cleveland Plain Dealer", summarized the film as follows: ""The Bomb" moves swiftly to cover Hiroshima and Nagasaki, the Cold War, the arms race, the Red Scare, the witch hunt, the Cuban Missile Crisis, test-ban treaties, the "Star Wars" initiative, the anti-nuke movement, the collapse of the Soviet Union and the rise of new nuclear threats."  According to historian Richard Rhodes, “The invention [of 'The Bomb'] was a millennial change in human history: for the first time, we were now capable of our own destruction, as a species.”
