An alumni of the Tisch School of the Arts, Marie received her Ph.D. in Performance Studies in 1991, with an emphasis on opera history in general and the works of Gian Carlo Menotti in particular, and is an adjunct professor teaching musical theatre history. A professional singer with experience in classical and operatic music, as well as musical theatre, she performed for over 20 years with a professional a’capella trio, The Salomone Trio, that specialized in Early Music and Jewish Music. The Salomone Trio performed at numerous venues throughout New York including Lincoln Center, Gracie Mansion and the 92nd Street Y. Their CD, “Sacred and Profane” was released in Fall 1998. The trio expanded their repertoire by presenting an original theatre piece, “Uppity Women of the Middle Ages,” written by Marie Costanza. Marie has also directed both musical theatre works and the classics off-off Broadway and in the tri-state area. She was a producer for the Off-Broadway production of “Mimi Le Duck” and acted as a production coordinator for The Italian-Heritage Opera Theatre and NYU’s Musical Theatre Hall of Fame. As her MA degree was in English/Creative Writing, she returned to her writing training and currently writes mystery novels and short stories.
