Question: Which Russian composer was a member of the group of composers known as The Five, Nikolai Rimsky-Korsakov or Mikhail Glinka?
Context: In mid- to late-19th-century Russia, Pyotr Ilyich Tchaikovsky and a group of composers known as The Five had differing opinions as to whether should be composed following Western or native practices.  Tchaikovsky wanted to write professional compositions of such quality that they would stand up to Western scrutiny and thus transcend national barriers, yet remain distinctively Russian in melody, rhythm and other compositional characteristics.  The Five, made up of composers Mily Balakirev, Alexander Borodin, César Cui, Modest Mussorgsky, and Nikolai Rimsky-Korsakov, sought to produce a specifically Russian kind of art music, rather than one that imitated older European music or relied on European-style conservatory training.  While Tchaikovsky himself used folk songs in some of his works, for the most part he tried to follow Western practices of composition, especially in terms of tonality and tonal progression.  Also, unlike Tchaikovsky, none of The Five were academically trained in composition; in fact, their leader, Balakirev, considered academicism a threat to musical imagination.  Along with critic Vladimir Stasov, who supported The Five, Balakirev attacked relentlessly both the Saint Petersburg Conservatory, from which Tchaikovsky had graduated, and its founder Anton Rubinstein, orally and in print. Mikhail Ivanovich Glinka (Russian: Михаи́л Ива́нович Гли́нка ; 1 June [O.S. 20 May] 1804 15 February [O.S. 3 February] 1857 ) was the first Russian composer to gain wide recognition within his own country, and is often regarded as the fountainhead of Russian classical music.  Glinka's compositions were an important influence on future Russian composers, notably the members of The Five, who took Glinka's lead and produced a distinctive Russian style of music. Nikolai Andreyevich Rimsky-Korsakov (18 March [O.S. 6 March] 1844 21 June [O.S. 8 June] 1908 ) was a Russian composer, and a member of the group of composers known as The Five.  He was a master of orchestration.  His best-known orchestral compositions—"Capriccio Espagnol", the "Russian Easter Festival Overture", and the symphonic suite "Scheherazade"—are staples of the classical music repertoire, along with suites and excerpts from some of his 15 operas.  "Scheherazade" is an example of his frequent use of fairy tale and folk subjects. Cleopatra (French: Cléopâtre ) is a dramatic ballet in one act, with choreography and libretto by Michel Fokine, and music by Anton Arensky, Alexander Taneyev, Nikolai Rimsky-Korsakov, Mikhail Glinka, Alexander Glazunov, Modeste Mussorgsky, Nikolai Tcherepnin. Russian Easter Festival Overture: Overture on Liturgical Themes (Russian: Светлый праздник, "Svetliy prazdnik" ), Op.  36, also known as the Great Russian Easter Overture, is a concert overture written by the Russian composer Nikolai Rimsky-Korsakov between August 1887 and April 1888.  It was dedicated to the memories of Modest Mussorgsky and Alexander Borodin, two members of the group of composers known in English as "The Five".  It is the last of what many call his three most exceptionally brilliant orchestral works, preceded by "Capriccio Espagnol" and "Scheherazade".  The work received its premiere at a Russian symphony concert in St. Petersburg in late December 1888. Pyotr Ilyich Tchaikovsky's relations with the group of composers known as the Belyayev circle, which lasted from 1887 until Tchaikovsky's death in 1893, influenced all of their music and briefly helped shape the next generation of Russian composers.  This group was named after timber merchant Mitrofan Belyayev, an amateur musician who became an influential music patron and publisher after he had taken an interest in Alexander Glazunov's work.  By 1887, Tchaikovsky was firmly established as one of the leading composers in Russia.  A favorite of Tsar Alexander III, he was widely regarded as a national treasure.  He was in demand as a guest conductor in Russia and Western Europe, and in 1890 visited the United States in the same capacity.  By contrast, the fortunes of the nationalistic group of composers known as The Five, which preceded the Belyayev circle, had waned, and the group had long since dispersed; of its members, only Nikolai Rimsky-Korsakov remained fully active as a composer.  Now a professor of musical composition and orchestration at the Saint Petersburg Conservatory, Rimsky-Korsakov had become a firm believer in the Western-based compositional training that had been once frowned upon by the group. Rimsky-Korsakov (Russian: Римский-Корсаков ) is a 1953 Soviet biopic directed by Gennadi Kazansky and Grigori Roshal and starring Grigori Belov, Nikolai Cherkasov and Aleksandr Borisov.  The film portrays the life of the Russian composer Nikolai Rimsky-Korsakov.  The film was shot in Sovcolor. Kamarinskaya (Russian: камаринская ) is a Russian traditional folk dance, which is mostly known today as the Russian composer Mikhail Glinka's composition of the same name.  Glinka's "Kamarinskaya", written in 1848, was the first orchestral work based entirely on Russian folk song and to use the compositional principles of that genre to dictate the form of the music.  It became a touchstone for the following generation of Russian composers ranging from the Western-oriented Pyotr Ilyich Tchaikovsky to the group of nationalists known collectively as The Five and was also lauded abroad, most notably by French composer Hector Berlioz. The Great Glinka (Russian: Глинка , "Glinka " ) is a 1946 Soviet biopic film directed by Lev Arnshtam.  The film is about Mikhail Glinka, a Russian composer of the 19th century.  The film was awarded the Stalin Prize of II degree (1947) and it was entered into the 1946 Cannes Film Festival. Capriccio espagnol, Op.  34, is the common Western title for a five movement orchestral suite, based on Spanish folk melodies, composed by the Russian composer Nikolai Rimsky-Korsakov in 1887.  Rimsky-Korsakov originally intended to write the work for a solo violin with orchestra, but later decided that a purely orchestral work would do better justice to the lively melodies.  The Russian title is Каприччио на испанские темы (literally, Capriccio on Spanish Themes).
