These two operas, Cavalleria rusticana by Pietro Mascagni and Pagliacci by Rugerro Leoncavallo, both had their world premieres in the last decade of the 19th century and in fact were first staged as a double bill at the Metropolitan Opera New York in December 1893.  They have both been hugely successful as a duet and indeed the original Director of this revival, Damiano Michieletto, has brought a common theme to the two operas, relocating them both to a small town in Southern Italy, with a bakery for the Cav and a community hall for the Pag.
