The conductor Hervé Niquet and the director Marshall Pynkoski return to the scene of their triumph with André Grétry’s rescue opera Richard Cœur de Lion, beloved of French royalists on the eve of the French Revolution. This time, they turn to a very different exercise in the same genre. La Caravane du Caire focuses on patriotic French soldiers on campaign in Egypt under Napoléon. Romance is in the air, under threat from human traffickers. Parallels with Mozart’s Abduction from the Seraglio have been suggested. —Matthew Gurewitsch
