Show Notes

In the late 1800s, an opera singer named Camille Monfort captivated audiences across Brazil with a voice so extraordinary, witnesses struggled to describe it. While accounts of her performances varied, those who saw her agreed on one thing — something about her presence felt otherworldly.
