coverage of these events, an immediate wave of outrage against the ban arose throughout Russia and abroad; liberals and intellectuals deluged the composer's residence with letters of sympathy, and even peasants who had not heard a note of Rimsky-Korsakov's music sent small monetary donations. Several faculty members of the St. Petersburg Conservatory resigned in protest, including Glazunov and Lyadov. Eventually, over 300 students walked out of the Conservatory in solidarity with Rimsky-Korsakov. By December he had been reinstated under a new director, Glazunov. Rimsky-Korsakov retired from the Conservatory in 1906. The political controversy continued with his opera The Golden Cockerel. Its implied criticism of monarchy, Russian imperialism and the Russo-Japanese War gave it little chance of passing the censors. The premiere was delayed until 1909, after Rimsky-Korsakov's death, and even then it was performed in an adapted version. In April 1907, Rimsky-Korsakov conducted a pair of concerts in Paris, hosted by impresario Sergei Diaghilev, which featured music of the Russian nationalist school. The concerts were hugely successful in popularizing Russian classical music of this kind in Europe, Rimsky-Korsakov's in particular. The following year, his opera Sadko was produced at the Paris Opéra and The Snow Maiden at the Opéra-Comique. He also had the opportunity to hear more recent music by European composers. He hissed unabashedly when he heard Richard Strauss's opera Salome, and told Diaghilev after hearing Claude Debussy's opera Pelléas et Mélisande, "Don't make me listen to all these horrors or I shall end up liking them!" Hearing these works led him to appreciate his place in the world of classical music. He admitted that he was a "convinced kuchkist" (after kuchka, the shortened Russian term for The Five) and that his works belonged to an era that musical trends had left behind. Death Beginning around 1890, Rimsky-Korsakov suffered from angina. While this ailment initially wore him down gradually, the stresses concurrent with the 1905 Revolution and its aftermath greatly accelerated its progress. After December 1907, his illness became severe, and he could not work. In 1908, he died at his Lubensk estate near Luga (modern day Plyussky District of Pskov Oblast), and was interred in Tikhvin Cemetery at the Alexander Nevsky Monastery in Saint Petersburg, next to Borodin, Glinka, Mussorgsky and Stasov. Compositions Rimsky-Korsakov followed the musical ideals espoused by The Five. He employed Orthodox liturgical themes in the Russian Easter Festival Overture, folk song in Capriccio Espagnol
