Throbbing through a darkly lit room, the live organ music of T. Desiree Hines texturizes the experience of watching a silent film and sets the mood for a more old-school Halloween. She’ll both improvise and draw from classical pieces during her accompaniment of Nosferatu, with reverberating notes enhancing the chill of one of the earliest films in the horror genre. “Before all the other Dracula movies,” says Hines, “there was Nosferatu.” Fri., Oct. 30, 7 and 11 p.m., $5-$10, First Unitarian Church, 2125 Chestnut St., 800-595-4849, traversetheater.tix.com.
