*On the back cover, there is a faint picture of Lieseil Inc. countryside mental estate as the background. The back cover is the same as side A but in a different colour. This could possibly show that both side A and side B are based around that building, and that possibly the actual ‘Boom Boom Room’ is inside the Mental Estate. After all, a Boom Boom Room is a room full of the Boom gas, like a gas chamber. The Mental Estate is where they experiment on patients with the gas, so it makes sense for the Boom Boom Room to be located there.

*At the bottom of the cover, there is a note saying ‘Warning: Life without great music is not cool. Thank you for keeping it alive.’
