Aida is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni, based on a scenario written by French Egyptologist Auguste Mariette. It was first performed at the Khedivial Opera House in Cairo on December 24, 1871.
The opera was met with great acclaim when it finally opened and continues to be a staple of the standard operatic repertoire. There are many recordings of it, and it is one of the most popular operas. Opera America claims it to be the sixteenth most performed opera in North America (photo: The Great Sphinx and the Pyramids of Giza /source: Wikipedia).
