This weekend found Marble City Opera’s final staged production of the year, Dominick Argento’s one-act work from 1971, ‘Postcard From Morocco’, in the event end of Jackson Terminal. The placement of a piece like Argento’s opera (libretto by John Donahue) in a space like the Terminal felt strangely natural—seven people find themselves waiting in a train station, all the while examining their existences in terms of their personal “baggage” in a surrealist dramatic environment. Dare I say it? It’s a bit like “Waiting For Godot in a Train Station.” And I mean that in the nicest—and most enticing—possible way.
