Question: Which composer who was a member of the group of composers known as The Five, put to music poems by Aleksey Vasilievich Koltsov?
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. 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. 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. 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. Alexis Emmanuel Chabrier (] ; January 18, 1841September 13, 1894) was a French Romantic composer and pianist.  Although known primarily for two of his orchestral works, "España" and "Joyeuse marche", he left an important corpus of operas (including "L'étoile"), songs, and piano music.  He was admired by composers as diverse as Debussy, Ravel, Richard Strauss, Satie, Schmitt, Stravinsky, and the group of composers known as Les six.  Stravinsky alluded to "España" in his ballet "Petrushka"; Gustav Mahler called "España" "the beginnings of modern music" and alluded to the "Dance Villageoise" in the "Rondo Burleske" movement of his Ninth Symphony.  Ravel wrote that the opening bars of "Le roi malgré lui" changed the course of harmony in France, Poulenc wrote a biography of the composer, and Richard Strauss conducted the first staged performance of Chabrier's incomplete opera "Briséïs". Aleksey Vasilievich Koltsov (Russian: Алексе́й Васи́льевич Кольцо́в ) (October 15, 1809 – October 29, 1842) was a Russian poet who has been called a Russian Burns.  His poems, frequently placed in the mouth of women, stylize peasant-life songs and idealize agricultural labour.  Koltsov earnestly collected Russian folklore which strongly influenced his poetry.  He celebrated simple peasants, their work and their lives.  Many of his poems were put to music by such composers as Dargomyzhsky, Mussorgsky, and Rimsky-Korsakov. George Whitefield Chadwick (November 13, 1854 – April 4, 1931) was an American composer.  Along with Horatio Parker, Amy Beach, Arthur Foote, and Edward MacDowell, he was a representative composer of what is called the Second New England School of American composers of the late 19th century—the generation before Charles Ives.  Chadwick's works are influenced by the Realist movement in the arts, characterized by a down-to-earth depiction of people's lives.  Many consider his music to portray a distinctively American style.  His works included several operas, three symphonies, five string quartets, tone poems, incidental music, songs and choral anthems.  Along with a group of other composers collectively known as the Boston Six, Chadwick was one of those responsible for the first significant body of concert music by composers from the United States.  The other five were Amy Beach, Arthur Foote, Edward MacDowell, John Knowles Paine, and Horatio Parker. Paul Hofhaimer (January 25, 1459 – 1537) was an Austrian organist and composer.  He was particularly gifted at improvisation, and was regarded as the finest organist of his age by many writers, including Vadian and Paracelsus; in addition he was one of only two German-speaking composers of the time (Heinrich Isaac was the other) who had a reputation in Europe outside of German-speaking countries.  He is grouped among the composers known as the Colorists. Ruth Crawford Seeger (July 3, 1901 – November 18, 1953), born Ruth Porter Crawford, was an American modernist composer active primarily during the 1920s and 1930s and an American folk music specialist from the late 1930s until her death.  She was a prominent member of a group of American composers known as the "ultramoderns," and her music influenced later composers including Elliott Carter . Diafana Krina (Greek: Διάφανα Κρίνα, which means in English: Transparent Lilies) was a Greek rock group.  It consisted of Thanos Anestopoulos (vocals, acoustic guitar, piano), Pantelis Rodostoglou (bass), Nikos Bardis (electric guitar, trumpet), Kyriakos Tsoukalas (electric guitar), Tassos Machas (drums) and (from 1996 until 2000) Panagiotis Berlis (keyboards, vocals).  Their special characteristic (apart from their distinct baritone voice of Anestopoulos) is that they set to music poems (most written by bassist Rodostoglou) rather than usual lyrics.
