Jessye Mae Norman was an American opera singer and recitalist. She was able to perform dramatic soprano roles, but did not limit herself to that voice type. A commanding presence on operatic, concert and recital stages, Norman was associated with roles including Beethoven's Leonore, Wagner's Sieglinde and Kundry, Berlioz's Cassandre and Didon, and Bartók's Judith. The New York Times music critic Edward Rothstein described her voice as a "grand mansion of sound", and wrote that "it has enormous dimensions, reaching backward and upward. It opens onto unexpected vistas. It contains sunlit rooms, narrow passageways, cavernous halls."

Les Troyens is a French grand opera in five acts, running for about five hours, by Hector Berlioz. The libretto was written by Berlioz himself from Virgil's epic poem the Aeneid; the score was composed between 1856 and 1858. Les Troyens is Berlioz's most ambitious work, the summation of his entire artistic career, but he did not live to see it performed in its entirety. Under the title Les Troyens à Carthage, the last three acts were premièred with many cuts by Léon Carvalho's company, the Théâtre Lyrique, at their theatre on the Place du Châtelet in Paris on 4 November 1863, with 21 repeat performances. The reduced versions run for about three hours. After decades of neglect, today the opera is considered by some music critics as one of the finest ever written.
