Question: Who's masterpiece is Cavalleria Rusticana,  Emmanuel Chabrier or Pietro Mascagni?
Context: Cavalleria rusticana (] ; Italian for "rustic chivalry") is an opera in one act by Pietro Mascagni to an Italian libretto by Giovanni Targioni-Tozzetti and Guido Menasci, adapted from a play and short story written by Giovanni Verga.  Considered one of the classic "verismo" operas, it premiered on 17 May 1890 at the Teatro Costanzi in Rome.  Since 1893, it has often been performed in a so-called "Cav/Pag" double-bill with "Pagliacci" by Ruggero Leoncavallo. Cavalleria rusticana is a 1982 Italian film directed by Franco Zeffirelli based on Pietro Mascagni's 1890 opera of the same name.  It stars tenor Plácido Domingo, mezzo-soprano Elena Obraztsova, and baritone Renato Bruson, all singing their own roles.  Georges Prêtre conducted the Teatro alla Scala Orchestra for the movie's soundtrack.  The film was made for broadcast on television.  In 2003, it was released on DVD by Deutsche Grammophon, paired with "Pagliacci", also starring Plácido Domingo and directed by Franco Zeffirelli. Pietro Antonio Stefano Mascagni (] ; 7 December 1863 – 2 August 1945) was an Italian composer most noted for his operas. His 1890 masterpiece "Cavalleria Rusticana" caused one of the greatest sensations in opera history and single-handedly ushered in the "Verismo" movement in Italian dramatic music.  While it was often held that Mascagni, like Leoncavallo, was a "one-opera man" who could never repeat his first success, "L'amico Fritz" and "Iris" have remained in the repertoire in Europe (especially Italy) since their premieres.  Mascagni said that at one point, "Iris" was performed in Italy more often than "Cavalleria" (cf. Stivender). Mala Pasqua!  (Bad Easter!)  is an opera in three acts composed by Stanislao Gastaldon to a libretto by Giovanni Domenico Bartocci-Fontana.  The libretto is based on Giovanni Verga's play, "Cavalleria rusticana" ("Rustic Chivalry") which Verga had adapted from his short story of the same name.  "Mala Pasqua!"  premiered on 9 April 1890 at the Teatro Costanzi in Rome, six weeks before Pietro Mascagni's opera "Cavalleria rusticana" which was also based on Verga's play.  Bartocci-Fontana's libretto adds some elements that were not in Verga's original and expands on others.  The name of the Santuzza character was also changed to Carmela, but the basic plot and setting remain the same.  Its title refers to the curse which Carmela places on Turiddu, the lover who had spurned her: "Mala Pasqua a te!"  ("May you have an evil Easter!") .  Following its Rome premiere "Mala Pasqua!"  had a few more performances in Perugia and Lisbon, but it was completely eclipsed by the phenomenal success of Mascagni's opera.  After the 1891 Lisbon run it was not heard again until 2010 when it was given a semi-staged performance in Agrigento, Sicily. Alexis Emmanuel Chabrier (] ; January 18, 1841September 13, 1894) was a French Romantic composer and pianist.  Although known primarily for two of his orchestral works, "España" and "Joyeuse marche", he left an important corpus of operas (including "L'étoile"), songs, and piano music.  He was admired by composers as diverse as Debussy, Ravel, Richard Strauss, Satie, Schmitt, Stravinsky, and the group of composers known as Les six.  Stravinsky alluded to "España" in his ballet "Petrushka"; Gustav Mahler called "España" "the beginnings of modern music" and alluded to the "Dance Villageoise" in the "Rondo Burleske" movement of his Ninth Symphony.  Ravel wrote that the opening bars of "Le roi malgré lui" changed the course of harmony in France, Poulenc wrote a biography of the composer, and Richard Strauss conducted the first staged performance of Chabrier's incomplete opera "Briséïs". Domenico Monleone (January 4, 1875 – 15 January 1942) was an Italian composer of operas, most noted for his opera "Cavalleria rusticana" of 1907, which for a while rivalled the success of Mascagni's work of the same name which was from the same source.  The work was the third opera to be based on Verga’s 1884 theatrical adaptation of his own short story, "Cavalleria rusticana", Stanislao Gastaldon’s "Mala Pasqua" (1888) being the first, and Mascagni's famous opera (1890) being the second. Signe Amundsen Finsland (9 June 1899 - 13 May 1987) was a Norwegian operatic soprano.  She studied singing in her native country with the soprano Mimi Hviid before making her professional debut at the Gamle Logen in Oslo in 1920.  She then pursued further voice studies in Rome with Rosina Storchia and made her Italian debut at the Teatro dell'Opera di Roma in 1925 as Norina in Gaetano Donizetti's "Don Pasquale".  She was heard at that house later that year as Rosina in Gioachino Rossini's "The Barber of Seville".  She was then heard in the title role of Giuseppe Verdi's "Aida" at La Scala, and during her time in Milan studied singing further with the conductor Antonio Votto.  She was soon heard at the Opéra-Comique in Paris as Santuzza in Pietro Mascagni's "Cavalleria rusticana".  After further engagements in the French provinces, she became a member of the National Theatre, Oslo where she remained active for the rest of her career.  As an educator, she was the singing teacher of Eva Gustavson. Mark Delavan is an American operatic bass-baritone.  He made his professional debut in 1986 at the San Francisco Opera in a small role in Giuseppe Verdi's "Don Carlos".  He spent the next three years performing in numerous comprimario roles with the company.  He has since returned to that opera house to sing Scarpia in Giacomo Puccini's "Tosca" (2004, with Carol Vaness in the title role) and Wotan in Richard Wagner's "The Ring Cycle" (2008, 2010, and 2011).  In 2001 he made his debut at the Metropolitan Opera as Amonasro in Verdi's "Aida" with Deborah Voigt in the title role, Luciano Pavarotti as Radamès, Olga Borodina as Amneris, and James Levine conducting.  He has since been heard at the Met as Alfio in Pietro Mascagni's "Cavalleria rusticana", Carlo Gérard in "Andrea Chénier", Count Tomsky in "The Queen of Spades", Don Carlo in Verdi's "La Forza del Destino", the Messenger in Richard Strauss' "Die Frau ohne Schatten", Scarpia, and the title roles in Verdi's "Nabucco", Verdi's "Rigoletto", and Verdi's "Simon Boccanegra". This is a discography of Cavalleria rusticana, an opera by Pietro Mascagni.  It premiered at the Teatro Costanzi in Rome on 17 May 17, 1890.  There have been over 100 full-length recordings of "Cavalleria rusticana" published since it was first recorded in Germany in 1909.  Mascagni himself has conducted the opera in two recordings, the best-known of which is the 1940 EMI recording made to mark the 50th anniversary of the opera's premiere.  The performance by the La Scala orchestra and chorus with Lina Bruna Rasa as Santuzza and Beniamino Gigli as Turiddu also has a spoken introduction by Mascagni.  Originally released as an LP, it is available on CD under several historical recording labels, including Naxos. "Read My Mind" is the first single by Sweetbox from the album "Jade," with Jade Villalon as a frontwoman.  "Read My Mind" samples "Cavalleria Rusticana" from Pietro Mascagni.
