Franz Anton Christoph Hilverding (1710–1768), aka Hilferding, was an Austrian choreographer and dancer.
 For a time Hilverding served as the director of the Imperial Theatre in St. Petersburg, Russia.
 Hilverding, simultaneously as his contemporaries Jean Baptiste de Hesse, and own assistant Gaspare Angiolini, contributed to the development of the Ballet d'Action, for which Jean Georges Noverre would get lasting credit with the publication of his Letters on Dancing and Ballets.
 Ballets d'action emphasized a cohesive dramatic and expressive element to performances, with costumes, plot, and movement all serving the purpose of the story.
 Hilverding studied in Paris from 1734 and 1736, and may have been inspired by the ballerina Marie Sallé, who was one of the first to explore this notion of cohesive dramatic ballets.
 He started creating dramatic ballets as court choreographer in Vienna in the 1740s, many using the stories of mythological lovers.
 Hilverding reworked Rameau's Le Turc Généreux (1758) from Lés Indes Galantes, which is immortalized in a print by Bernardo Bellotto entitled Le Turc Généreux.
 Ballet Pantomime executé à Vienne sur le théâtre de la cour, le 26 Avril 1758, in the British Museum.
 Invited by Czarina Elizabeth in 1758, he became court choreographer in St Petersburg.
 He brought his dancers with him to Russia, and did much to progress the talent of the Russian dancers.
 He tried to use Russian themes in his ballets, and depicted Russia as the "Defender of Virtue" in his "Virtue's Refuge."
 Hilverding returned to Vienna in 1764 and staged "Le Triomphe de l'Amour" which starred Marie Antoinette and her brothers Ferdinand and Archduke Maximilian Francis of Austria.
György Ligeti (] ; born 19 December 1972) is a Hungarian indie musician, record producer, best known as the lead singer, songwriter, lyricist and guitarist of the indie rock band We Are Rockstars, and the disbanded The Puzzle.
 He is also the singer and guitarist of the Hungarian electro band, Žagar.
 He is not related to the avant-garde classical composer of the same name, György Ligeti (1923-2006).
Atmosphères is a piece for full orchestra, composed by György Ligeti in 1961.
 It is noted for eschewing conventional melody and metre in favor of dense sound textures.
 After "Apparitions", it was the second piece Ligeti wrote to exploit what he called a "micropolyphonic" texture.
 It gained further exposure after being used in Stanley Kubrick's film "".
Musica ricercata is a set of eleven pieces for piano by György Ligeti.
 The work was composed from 1951 to 1953, shortly after the composer began lecturing at the Budapest Academy of Music.
 The work premiered on 18 November 1969 in Sundsvall, Sweden.
 Although the ricercata (or ricercar) is an established contrapuntal style (and the final movement of the work is in that form), Ligeti's title should probably be interpreted literally as "researched music" or "sought music".
 This work captures the essence of Ligeti's search to construct his own compositional style "ex nihilo", and as such presages many of the more radical directions Ligeti would take in the future.
Noémi Rime is a French soprano.
 She regularly appears in opera productions by William Christie's Les Arts Florissants ensemble.
 Her roles have included Cleone in "Médée", Dido in "Dido and Aeneas", and Fatime in "Les Indes galantes".
 She currently teaches on the faculty of the Conservatoire à rayonnement régional de Poitiers.
Steven Cole (born 1949) is an American opera singer.
 He is particularly known for his portrayal of tenor character roles in an international career spanning more than 30 years.
 He sang in the world premieres of Jean Prodromides's "La Noche Triste", Gavin Bryars's "Medea", and the revised version of György Ligeti's "Le Grand Macabre".
The Pièces de clavecin en concerts, published in 1741, constitute the only chamber music by Jean-Philippe Rameau and were composed in full maturity; they came after his music for solo harpsichord, and just before "Les Indes galantes".
Le Grand Macabre (1974–77, revised version 1996) is György Ligeti's only opera.
 The opera has two acts, and its libretto – based on the 1934 play, "La balade du grand macabre", by Michel De Ghelderode – was written by Ligeti in collaboration with , director of the Stockholm puppet theatre.
 The original libretto was written in German, as "Der grosse Makaber", but for the first production was translated into Swedish by Meschke under its current title .
 The opera has been performed also in English, French, Italian, Hungarian and Danish.
 Only a few notes need be changed to perform the opera in any of these languages.
Philippe Courbois (fl.
 1705-1730) was a French Baroque composer.
 It is commonly stated that he was maître de musique of the Duchess of Maine, but Michele Cabrini convincingly refutes this claim in his edition of Courbois's cantatas.
 At least three of his masses were performed for the King of France at Versailles.
 Sometime before 1710, Courbois published a book of seven cantatas with texts by Louis Fuzelier, who would later write the libretto of "Les Indes Galantes."
 It is these cantatas for which he is most famous today
In 1725, French settlers in Illinois sent Chief Agapit Chicagou of the Mitchigamea and five other chiefs to Paris.
 On 25 November 1725, they met with King Louis XV.
 Chicagou had a letter read pledging allegiance to the crown.
 They later danced three kinds of dances in the Théâtre-Italien, inspiring Rameau to compose his rondeau "Les Sauvages".
