Which composer created Requiem which was commissioned by Soli Deo Gloria for the 2003 bicentennial of the birth of French composer Hector Berlioz?
Hector Berlioz Louis-Hector Berlioz (] (English: ); 11 December 1803 – 8 March 1869) was a French Romantic composer, best known for his compositions "Symphonie fantastique" and "Grande messe des morts" (Requiem). Berlioz made significant contributions to the modern orchestra with his "Treatise on Instrumentation". He specified huge orchestral forces for some of his works, and conducted several concerts with more than 1,000 musicians. He also composed around 50 songs. His influence was critical for the further development of Romanticism, especially in composers like Richard Wagner, Nikolai Rimsky-Korsakov, Franz Liszt, Richard Strauss, and Gustav Mahler.
Gloria (opera) Gloria is a tragic opera in three acts by Francesco Cilea with an Italian libretto by Arturo Colautti. A variation on the Romeo and Juliet story and set in 14th century Siena, the libretto is based on Victorien Sardou's 1874 play "La Haine" ("Hatred"). The opera premiered on 15 April 1907 at La Scala conducted by Arturo Toscanini with Salomea Krusceniski in the title role. "Gloria" was a failure at its premiere when it was withdrawn after two performances and fared little better in the 1932 revised version, although there have been two late 20th century revivals. It proved to be Cilea's last staged opera. In the 43 years following the premiere of "Gloria" he worked on two or three further operas which were never performed and continued to compose chamber and orchestral music.
