So! confession time.
The first time I listened to Ghost Quartet i didnt knew anything about it except it was made by Dave Malloy. In that time I didnt even knew much about Dave, I just had listen some songs from The Great Comet and… that was it. So I didnt have any idea of the cast, or the plot, or anything really. I guess my mind took some inspiration and tried to made something with the whole Rose Red / Pearl White, and… this is it! Just my (first) own representation of their name/souls.
