Since (at least) the Greeks, humorists, moralists and satirists have been fascinated by the artistic game of inversion, of “the world turned upside down”, which is how one might translate the title of this largely forgotten opera by Salieri. It here gets its first ever recording. Present an image of society turned on its head and you enable your audience/reader/viewer to see the actual way of things in a whole new light. Your aims may be to expose the follies and errors of the actual, to propose a better way of doing things, or simply to get some laughs from the resulting improbabilities and surprises - or, of course, a mixture of all these motives and more.
