The concert, directed by Austin Regan, will feature Van Hughes (American Idiot, 9 to 5, Hairspray) and Christy Altomare (Mamma Mia!, Carrie: the Musical) as well as a full chorus.
The Sacred Harp, press notes state, concerns "the nephew of a preacher who tries to break free from his Appalachian confines by building an enchanted guitar."
