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).
Salvatore Giuliano is an opera in one act by Lorenzo Ferrero to an Italian-language libretto by Giuseppe Di Leva, which was conceived to be performed in tandem with Pietro Mascagni's "Cavalleria rusticana".
 The work was commissioned by the Teatro dell'Opera di Roma and premiered there on 25 January 1986.
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".
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.
Daniele Barioni (born September 6, 1930 in Copparo, Ferrara, Italy) is an Italian opera singer who had a prolific career during the 1950s through the 1970s.
 Early on in his career he rose to fame as a leading tenor at the Metropolitan Opera between 1956 and 1962.
 Afterwards he worked primarily in opera houses and concerts throughout the United States, although he did make numerous appearances in both Europe and South America as well.
 Barioni was particularly associated with the operas of Giacomo Puccini and the roles of Turiddu in Pietro Mascagni's "Cavalleria rusticana" and Alfredo in Giuseppe Verdi's "La traviata".
Georges Bizet (] ; 25 October 18383 June 1875), registered at birth as Alexandre César Léopold Bizet, was a French composer of the romantic era.
 Best known for his operas in a career cut short by his early death, Bizet achieved few successes before his final work, "Carmen", which has become one of the most popular and frequently performed works in the entire opera repertoire.
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.
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.
