Question: Who is often associated with impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term, and said of a Spanish composer  "He will become "the" Spanish composer of our century"?
Context: Flute, viola and harp are the instruments of a chamber music grouping that have become common through the establishment of ensembles that feature this set of instruments and have enjoyed new compositions written for the set.  The first major composition written for the instruments was the Sonata for flute, viola and harp (1915) by Claude Debussy; Debussy had set out to compose a set of chamber works for "diverse ensembles," as distinguished from more common groupings like string quartet or piano trio.  Though other composers have written chamber works that feature harp, this set of instruments has gained a repertoire, which places it among other established genres of the twentieth century such as the "Pierrot ensemble" (flute, clarinet, piano, violin and cello, with frequently added percussion or voice). The Seduction of Claude Debussy is a 1999 concept album by Art of Noise, featuring a line-up of Trevor Horn, Anne Dudley, Paul Morley, and Lol Creme.  Also appearing on the album are John Hurt, soprano Sally Bradshaw, Rakim, and Donna Lewis.  The group blended the music of French impressionist composer Claude Debussy with drum and bass, opera, hip hop, jazz, and narration, and described the album as "the soundtrack to a film that wasn't made about the life of Claude Debussy." Achille-Claude Debussy (] , 22 August 1862 – 25 March 1918), known since the 1890s as Claude-Achille Debussy or Claude Debussy, was a French composer.  He and Maurice Ravel were the most prominent figures associated with Impressionist music, though Debussy disliked the term when applied to his compositions.  He was made Chevalier of the Legion of Honour in 1903.  He was among the most influential composers of the late 19th and early 20th centuries, and his use of non-traditional scales and chromaticism influenced many composers who followed. Antonio José Martínez Palacios (12 December 190211 October 1936), professionally known as Antonio José, was a Spanish composer.  Maurice Ravel apparently said of Antonio José: "He will become "the" Spanish composer of our century", however, his music lay forgotten until the 1980s. Federico Moreno Torroba (3 March 189112 September 1982) was a Spanish composer, conductor, and theatrical impresario.  He is especially remembered for his important contributions to the classical guitar repertoire, becoming one of the leading twentieth-century composers for the instrument.  He was also one of the foremost composers of zarzuelas, a form of Spanish light opera.  His 1932 zarzuela, "Luisa Fernanda", has proved to be enduringly popular.  In addition, he composed ballets, symphonic works, and piano pieces, as well as one-act operas and one full-length opera, "El poeta", which premiere in 1980, starring well-known tenor Plácido Domingo.  Moreno Torroba also ran his own zarzuela company, which toured extensively, especially in Latin America. "Fantaisie" for piano and orchestra, L. 73, is a composition for piano and orchestra by French composer Claude Debussy.  It was composed between October 1889 and April 1890 but it received its first public performance only in 1919, a year after Debussy's death, in London by the Royal Philharmonic Orchestra with Alfred Cortot as soloist.  It is Debussy's only composition for piano and orchestra and, even though it is written in a three movement form, it was not composed as a Piano Concerto.  Today it is one of Debussy's least frequently performed works. 　This work is dedicated to the pianist René Chansarel, who had been scheduled to play the solo part for the cancelled premiere in 1890. Joseph Maurice Ravel (] ; 7 March 1875 – 28 December 1937) was a French composer, pianist and conductor.  He is often associated with impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term.  In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer. Adolfo Salazar Ruiz de Palacios (6 March 1890 - 27 September 1958) was a Spanish music historian, music critic, composer, and diplomat of the first half of the twentieth century.  He was the preeminent Spanish musicologist of the Silver Age.  Fluent in Spanish, French, and English, he was an intellectual and expert of the artistic and cultural currents of his time, and a brilliant polemicist.  He maintained a close connection with other prominent Spanish intellectuals and musicians including José Ortega y Gasset, Jesús Bay y Gay, and Ernesto Halffter.  In his writings, he was a defender of the French musical aesthetic of Maurice Ravel and Claude Debussy. José Evangelista (born 5 August 1943) is a Spanish composer and music educator who is based in Montreal, Canada.  A member of the Canadian League of Composers, the Sociedad General de Autores y Editores, and an associate of the Canadian Music Centre, Evangelista is known for his commitment to contemporary classical music and non-Western music.  In 1974 he was awarded first prize in the Confederación Espanola de Cajas de Ahorros Contest in Madrid for his "En guise de fête".  In 1978 he helped found "Les Événements du neuf", a concert society dedicated to avant-garde music.  In 1982 he was awarded a special prize from Spain's Ministry of Culture for his work "Vision", and in 1988 he won first prize in the choral works competition of St Mary Magdalene's Church in Toronto for his "O quam suavis est".  Since 1972 he has taught on the music faculty of the Université de Montréal.  Among his notable pupils is composer Analia Llugdar. Miguel Ángel Coria Varela (born 24 October 1937 – 24 February 2016) was a Spanish composer of classical music.  His early work showed affinities to the music of Anton Webern, but he became increasingly influenced by Impressionism.  From 1973 he entered his post-modern period where his compositions were marked by "attempts to evoke the spirit of the music of the past, but without literal allusions".  In addition to his instrumental music, he also composed an opera, "Belisa", which premiered at the Teatro de la Zarzuela in 1992.  Coria served as the Administrative Director of the RTVE Symphony Orchestra and Chorus in the 1980s and was a co-founder of ALEA, Spain's first laboratory for electronic music.
