Giovanni Guicciardi (12 January 1819 – 4 October 1883) was an Italian opera singer who sang leading baritone roles in the opera houses of Italy and Portugal.
 He is most remembered today for having created the role of Count di Luna in Verdi's "Il trovatore", although he created several other leading roles in operas by lesser known Italian composers.
 He accumulated a considerable fortune during the course of his career.
 After his retirement from the stage, he taught without payment in music schools in his native city, Reggio Emilia, and presided over a charity for orphaned musicians.
 He died in San Polo d'Enza at the age of 64.
Corrado Zambelli (3 June 1897 - 1 September 1974) was an Italian classical bass who had an active international singing career in operas and concerts from the 1920s through the 1950s.
 He appears on several complete opera recordings, including "Otello" and "Carmen" for His Master's Voice; and "Ernani", "Il trovatore", "La favorite", and "La Gioconda" for Columbia Records.
This is a partial discography of Giuseppe Verdi's opera "Il trovatore" ("The Troubadour") and "Le trouvère" (the revised version in French translation).
 At least 83 recordings exist of the opera as a whole, made between 1912 and 2011, although not all of them are absolutely complete.
 Of these, 45 are live audio recordings, 22 are studio audio recordings, and 16 are videos or movies.
 "Il trovatore" was first performed at the Teatro Apollo, Rome on 19 January 1853.
 "Le trouvère" was first presented on 12 January 1857.
Gaetano Fraschini (16 February 1816 – 23 May 1887) was an Italian tenor.
 He created many roles in 19th century operas, including five composed by Giuseppe Verdi.
 His voice was "heroic ... with a baritonal quality, ... yet Verdi and Donizetti appreciated his ability to sing softly and with subtlety."
 An Italian biographer has pointed out Fraschini's role in extending the longevity of Donizetti's operas, while at the same time accelerating the ascent of Verdi's repertory.
 He was indeed the most prominent singer who facilitated the transition from Donizetti to Verdi.
 Fraschini sang over one hundred roles and Verdi placed him at the top of his favorite tenors' list and described him as a "natural Manrico" for his "Il trovatore".
 Fraschini also played a pivotal role in the success of many operas by Pacini and Mercadante.
Alcina (HWV 34) is an opera seria by George Frideric Handel.
 Handel used the libretto of "L'isola di Alcina", an opera that was set in 1728 in Rome by Riccardo Broschi, which he acquired the year after during his travels in Italy.
 Partly altered for better conformity, the story was originally taken from Ludovico Ariosto's "Orlando furioso" (like those of the Handel operas "Orlando" and "Ariodante"), an epic poem.
 The opera contains several musical sequences with opportunity for dance: these were composed for dancer Marie Sallé.
Il trovatore (] ; Italian for "The Troubadour") is an opera in four acts by Giuseppe Verdi to an Italian libretto largely written by Salvadore Cammarano, based on the play "El trovador" (1836) by Antonio García Gutiérrez.
 It was Gutiérrez's most successful play, one which Verdi scholar Julian Budden describes as "a high flown, sprawling melodrama flamboyantly defiant of the Aristotelian unities, packed with all manner of fantastic and bizarre incident."
Vincenzo Moscuzza (1827–1896) was an Italian composer.
 Born in Syracuse, Sicily, he was the son of composer Luigi Moscuzza, and his initial musical training was from his father.
 He later studied at the Naples Conservatory with Saverio Mercadante.
 He is chiefly known for his many operas, of which his most successful were "Stradella il trovatore" (1850), "Don Carlo" (1862), and "Gonzales Davila" (1869).
 He died in Naples.
Frank Guarrera (December 3, 1923 – November 23, 2007) was an Italian-American lyric baritone who enjoyed a long and distinguished career at the Metropolitan Opera, singing with the company for a total of 680 performances.
 He performed 35 different roles at the Met, mostly from the Italian and French repertories, from 1948 through 1976.
 His most frequent assignments at the house were as Escamillo in Georges Bizet's "Carmen", Marcello in Giacomo Puccini's "La Bohème", Valentin in Charles Gounod's "Faust", and Ping in Puccini's "Turandot".
 He was also an admired interpreter of Mozart roles, establishing himself in the parts of both Guglielmo and Don Alfonso in "Così fan tutte" and Count Almaviva in "Le nozze di Figaro".
 Most of the roles he portrayed were from the lyric repertoire, such as the title role in Tchaikovsky's "Eugene Onegin", but he also sang some heavier roles at the Met like Amonasro in "Aïda", Jack Rance in "La fanciulla del West" and Il conte di Luna in "Il trovatore".
Ferrucio Calusio (1889 or 1890 - 3 June 1983) was an Argentine conductor.
 He began his career in the 1920s at La Scala in Milan, Italy as an assistant conductor to Arturo Toscanini.
 In 1927 he returned to his native country to join the conducting staff of the Teatro Colón in Buenos Aires.
 He served as one of that house's main conductors in the Italian repertoire through 1960.
 He also worked as a guest conductor with several important opera houses during his career, including conducting several operas at La Scala in the 1930s and at the Metropolitan Opera ("Cavalleria rusticana", "Pagliacci", and "Il trovatore") in 1940-1941.
 In 1939 he conducted the orchestra of La Scala for the first recording of Claudio Monteverdi's "L'Orfeo".
 He died in Buenos Aires at the age of 93.
Rolando Panerai (born 17 October 1924) is an Italian baritone, particularly associated with the Italian repertory.
 He was born in Campi Bisenzio, near Florence, Italy and studied with Frazzi in Florence and Armani and Giulia Tess in Milan.
 Panerai made his stage debut in 1947 in Naples at the Teatro di San Carlo as the pharaon in Rossini's "Mosè in Egitto".
 Other debuts, both in 1951, were as Simon Boccanegra in "Simon Boccanegra" in Bergamo and as Sharpless in "Madama Butterfly" at La Scala in Milan.
 He sang in many rarely performed Verdi operas on radio broadcast for RAI in 1951 (to commemorate the 50th anniversary of Verdi's death), such as "Giovanna d'Arco", "La battaglia di Legnano", and "Aroldo".
 Later roles included most of the great Verdi baritone roles, particularly the title character in "Rigoletto", The Count of Luna in "Il trovatore", Giorgio Germont in "La traviata", Marquis of Posa in "Don Carlos", Amonasro in "Aida".
