The 2021 edition of the Macerata Opera Festival was inaugurated with the same opera chosen in 1921 by Count Pier Alberto Conti. At that time, the Sferisterio, formerly a stadium for an ancient ball game, was turned into a venue for opera performances. 2021 was actually a double celebration: Aida, one of the most loved operas, premiered in Cairo in 1871, so this marks its 150th anniversary. Aida has become Verdi's most popular work. This highlight in the international repertoire is a challenge for the musical and scenic resources of an opera house. At the opening ceremony of the Suez Canal in 1869, Verdi’s Rigoletto was played. When the Opera House Cairo asked Verdi for a new work with an Egyptian story, he studied in detail Egyptian music and history in order to give his opera an exotic atmosphere. Performed at the Arena Sferisterio 23 July and 1, 7, 12 August 2021.
