It’s the second night of Previews for Masquerade, and I’ve just finished seeing Andrew Lloyd Webber’s newest immersive musical take on Phantom of the Opera. While comparing notes with a friend from the NYC immersive community, a man dressed in black approaches. Leaning in conspiratorially, he quietly tells me: “You see? Everything I told you was true.”
The man who approached me was a ghost hunter named Sean Hunter, who was at the center of a months-long alternate reality game teasing the release of Masquerade. The musical just finished Previews with a gala event, last night. To celebrate, here’s an overview of how we got to the Masquerade.

The Masquerade ARG: A Popup Homage to New York City
At its core, Masquerade teased the show’s existence with a series of popup experiences, celebrating New York City. As ARGNet previously reported, it started with the immersive show’s historic venue itself: to prepare for the show’s transformation, the windows of Lee’s Art Shop were liberally covered with newspapers. Upon closer inspection, however, many of these papers were referencing the history of Phantom of the Opera in New York City. And scattered in between the real papers from the city were a few in-universe papers about L’Opera Populaire.
Shortly after fans noticed this detail, a series of masks started popping up at locations across the city, with luggage tags bearing MasqueradeNYC.com on one side, and the message “if found please call 212-505-5666”. Calling the number (now Masquerade‘s business line) would trigger a voicemail message featuring a music box playing the song Masquerade, slowly winding down before an ominous voice states “he’s back”. The following day, a series of mirrors with the Masquerade logo appeared across the city. Each time, the MasqueradeNYC Instagram would post a story with a picture of where to go, for those curious enough (and quick enough) to find it. A full accounting of these events is listed below.
