NYMFomaniacs, rejoice! The impressive annual feast of new musical theater takes over multiple venues on 42nd Street for its 16th annual edition. Selections include 30 productions, readings, concerts and other events. Among the full stagings: Riley Thomas's My Real Mother, about the bond between a birth mother and the women who adopts her child; Cordelia O'Driscoll and Tom Williams's Buried, a romantic comedy about serial killers; Leo Schwartz and DC Cathro's Till, about the murder of a black teenager in 1955; and Yuri Worontschak and Paul Western-Pittard's Illuminati Lizards from Outer Space, about exactly what it sounds like it's about. Buried treasure could lie anywhere, so dig around.
