  Title: Pietro Mascagni
  Passage: 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).

  Passage: La conversione e morte di San Guglielmo ("The Conversion and Death of Saint William") is a sacred musical drama ("dramma sacro") in three parts by the Italian composer Giovanni Battista Pergolesi.  The libretto, by Ignazio Mancini, is based on the life of Saint William of Aquitaine as recounted by Laurentius Surius.  It was Pergolesi's first operatic work, possibly written as a study exercise for his conservatory.  The work was premiered at the Monastery of Sant'Agnello Maggiore, Naples in the summer of 1731.

The production was marred when the leading man Nicolo Grimaldi "Nicolini" fell fatally ill before the performance and an inexperienced substitute Gioacchino Conti "Gizziello" had to be called in at the last minute.  "La Salustia" was Pergolesi's first opera seria.  The story is based on the life of the Roman emperor Alexander Severus and his wife Sallustia Orbiana.
