She was also organist for the Paul Winter Consort at the cathedral's Easter and Christmas services and performed with the ensemble on their Grammy Award-winning album Silver Solstice, released in 2005.

[7][8] As organist at the Episcopalian edifice, Papadakos eschewed a staid, conservative style of music-making in favor of a creative, improvisational approach.

[9] She also had to cope with the acoustic challenges of playing in such an immense space, with an eight-second reverberation time, as she demonstrated to a Smithsonian magazine reporter in 1997.

[11] In the wake of the September 11, 2001, terrorist attack in Manhattan, Papadakos performed in "An Evening of Peace" gathering at nearby Riverside Church, joining other activists including Vietnamese Buddhist monk Thích Nhất Hạnh, Judy Collins, and Paul Winter.

[7] After visiting the ruins of Pompeii in Italy, Papadakos began writing a stage play about life in the ancient Roman city that ended in 79 AD with the cataclysmic eruption of Mt.

[19] Papadakos makes frequent appearances providing improvised organ music to accompany silent film screenings, a genre she began to play at the Cathedral when asked to fill in as a last-minute substitute for theater organist Lee Erwin.

[20][21] In the early 2000s, Papadakos started her annual Halloween Horror Tour,[22] which brings silent film's classics, such as Dr. Jekyll and Mr. Hyde[23] and Phantom of the Opera[24] to life on the world's pipe organs.

Her silent film appearances have included such classics as a rendition of the Hunchback of Notre Dame at a New Year's Eve 2011 celebration at Grace Cathedral, San Francisco, and Nosferatu at Kansas City's Kauffman Center for the Performing Arts organ in 2014.

[25] Using fictional characters, such as the wicked "Fire Witch", to portray global warming, the book seeks to present these issues in an understandable fantasy appealing to a broad audience.
