The Legend is a one-act tragic opera composed by Joseph Carl Breil to an English libretto by Jacques Byrne.
 It premiered at the Metropolitan Opera in New York City on March 12, 1919 in a triple bill with two other one-act operas, John Hugo's "The Temple Dancer" and Charles Cadman's "Shanewis".
 Its melodramatic story is set in Muscovadia, a mythical country in the Balkans, and involves an impoverished nobleman turned bandit, his daughter Carmelita, and her lover Stephen, a captain in the hussars.
 The action unfolds over a single night at the end of which both lovers are dead—Stephen stabbed to death by Carmelita and Carmelita shot by Stephen's fellow hussars.
 The only one of Breil's six operas to be performed by a major opera company, "The Legend" received scathing press reviews and after its three performances at the Met disappeared from the repertory.
Der Freischütz , Op. 77, J. 277, (usually translated as "The Marksman" or "The Freeshooter") is a German opera with spoken dialogue in three acts by Carl Maria von Weber with a libretto by Friedrich Kind.
 It premiered on 18 June 1821 at the Schauspielhaus Berlin.
 It is considered the first important German Romantic opera, especially in its national identity and stark emotionality.
Louis D'Angelo (May 6, 1888 – August 9, 1958) was an American bass-baritone of Italian birth who was particularly known for his performances at the Metropolitan Opera during the first half of the 20th century.
 He created roles in the world premieres of seven operas at the Met, including Marco in Puccini's "Gianni Schicchi" in 1917.
Magic Hunter (Hungarian: "Bűvös vadász" , French: "Freischütz" ) is a 1994 Hungarian-Swiss-French fantasy film written and directed by Ildikó Enyedi and loosely inspired to the opera Der Freischütz.
"O mio babbino caro " ("Oh My Beloved Father") is a soprano aria from the opera "Gianni Schicchi" (1918) by Giacomo Puccini to a libretto by Giovacchino Forzano.
 It is sung by Lauretta after tensions between her father Schicchi and the family of Rinuccio, the boy she loves, have reached a breaking point that threatens to separate her from Rinuccio.
 It provides an interlude expressing lyrical simplicity and single-hearted love in contrast with the atmosphere of hypocrisy, jealousy, double-dealing, and feuding in the medieval Florence of Puccini's only comedy.
 It provides the only set-piece in the through-composed opera.
This is a list of the recordings of Gianni Schicchi, the third of a group of three one-act operas by Giacomo Puccini collectively known as "Il trittico"; the other operas are "Il tabarro" and "Suor Angelica".
 The three were premiered at the Metropolitan Opera on 14 December 1918, and for the next three years were always played together.
 After 1921, however, Puccini agreed that the operas could be performed separately. "
Gianni Schicchi" became the most popular and most frequently performed of the three, often paired with other works such as Maurice Ravel's "L'heure espagnole" and Richard Strauss's "Salome".
Spanish tenor Plácido Domingo has officially sung 147 roles in Italian, French, German, English, Spanish and Russian.
 His main repertoire however is Italian ("Otello", Cavaradossi in "Tosca", "Don Carlo", Des Grieux in "Manon Lescaut", Dick Johnson in "La fanciulla del West", Radames in "Aida"), French ("Faust", "Werther", Don José in "Carmen", Samson in "Samson et Dalila"), and German ("Lohengrin", "Parsifal", and Siegmund in "Die Walküre").
 Domingo currently continues to add more operas to his repertoire.
 Since 2009, he has moved substantially into the baritone repertoire, especially focusing on Verdi baritone roles.
 In 2015, he made his most recent debuts as Macbeth at the Berliner Staatsoper, Don Carlo in "Ernani" at the Metropolitan Opera, and Gianni Schicchi at the Los Angeles Opera.
 Tim Page, a Pulitzer Prize-winner for music criticism, described Domingo in a 1996 "Washington Post" article as "the most versatile, intelligent and altogether accomplished operatic tenor now before the public."
Giuseppe De Luca (25 December 1876 – 26 August 1950), was an Italian baritone who achieved his greatest triumphs at the Metropolitan Opera in New York City.
 He notably created roles in the world premieres of two operas by Giacomo Puccini: Sharpless in "Madama Butterfly" (at La Scala, Milan, 1904) and the title role in "Gianni Schicchi" (Metropolitan Opera, 1918).
Gianni Schicchi (] ) is a comic opera in one act by Giacomo Puccini to an Italian libretto by Giovacchino Forzano, composed in 1917–18.
 The libretto is based on an incident mentioned in Dante's "Divine Comedy".
 The work is the third and final part of Puccini's "Il trittico" (The Triptych)—three one-act operas with contrasting themes, originally written to be presented together.
 Although it continues to be performed with one or both of the other "trittico" operas, "Gianni Schicchi" is now more frequently staged either alone or with short operas by other composers.
 The aria "O mio babbino caro" is one of Puccini's best known, and one of the most popular arias in opera.
Il trittico ("The Triptych") is the title of a collection of three one-act operas, "Il tabarro", "Suor Angelica", and "Gianni Schicchi", by Giacomo Puccini.
 The work received its world premiere at the Metropolitan Opera on 14 December 1918.
