Don Giovanni.

[porphyry]

 While feeding the Augsutulus, I've been playing the new Met production of Don Giovanni n the background. I notice that throughout the first few scenes the backdrop on stage is a New Oreleans whore house, complete with whores standing on the balconies. In the middle of Leporello's catalog aria, the whore house set separates and slides off into the wings, to reveal behind it...another New Orleans Whore house.
