At first, sound artist Lisa and former academic David think the strange chant crackling out of a pirate radio station might just be experimental music gone wrong or an off-key choir.

But in seeking the source of the broadcast, Lisa and David are drawn deep into a sonic mystery. Deciphering aural clues with acoustic archeology, they uncover a secret history spanning Ancient Mesopotamia, Cold War Germany, and contemporary New York.

A slow-burn thriller featuring original music by renowned composers Kamala Sankaram and Drew Fleming, the story is driven by the exploration of recording technologies, musical tunings, and mystical roots. What strange forces will these occult tunings unlock?
