Rise, Rapture, Rise

Early on in Phase One of "Something in the Sea", a record player appeared on Mark Meltzer's shelf, placed by the Big Sister. The record feature a theme of opera with a sense of patriotism, the words sung by an unknown female. The creator of the song is Sander Cohen. The first few minutes of the song are relatively normal, though at the end the song is cut off and eerily replaced by a little girl's voice, saying "Daddy? Where are you Daddy? Are you going to come and find me?" These words are presumably made by Mark's daughter, Cindy.

Lyrics
''Oh rise, Rapture rise! We turn our hopes up to the skies! Oh rise, Rapture rise! Upon your wings our dreams will fly A city in the ocean deep A promise that we'll always keep To boldly turn our eyes upon the prize! So rise, rise, rise! Oh rise, Rapture rise! We merrily we sing this reprise Oh rise, Rapture rise! To help us crush parasites despised A city on Poseidon's floor A set of ideas we adore A philosophy﻿ we all can emphasize So rise, ris-''

''Daddy? Where are you Daddy? Are you going to come and find me?''
