full_context: Document 1: Jean Sibelius: Jean Sibelius ( ;    ), born Johan Julius Christian Sibelius (8 December 186520 September 1957), was a Finnish composer and violinist of the late Romantic and early-modern periods. He is widely recognized as his country's greatest composer and, through his music, is often credited with having helped Finland to develop a national identity during its struggle for independence from Russia.
Document 2: Arturo Toscanini: Arturo Toscanini (] ; March 25, 1867 – January 16, 1957) was an Italian conductor. He was one of the most acclaimed musicians of the late 19th and of the 20th century, renowned for his intensity, his perfectionism, his ear for orchestral detail and sonority, and his eidetic memory. He was at various times the music director of La Scala in Milan, the Metropolitan Opera in New York, and the New York Philharmonic. Later in his career he was appointed the first music director of the NBC Symphony Orchestra (1937–54), and this led to his becoming a household name (especially in the United States) through his radio and television broadcasts and many recordings of the operatic and symphonic repertoire. Toscanini had absolute pitch.
Document 3: Bedřich Smetana: Bedřich Smetana (] ; 2 March 1824 – 12 May 1884) was a Czech composer who pioneered the development of a musical style which became closely identified with his country's aspirations to independent statehood. He is thus widely regarded in his homeland as the father of Czech music. Internationally he is best known for his opera "The Bartered Bride" and for the symphonic cycle "Má vlast" ("My Homeland"), which portrays the history, legends and landscape of the composer's native land.
Document 4: Symphony No. 8 (Sibelius): Jean Sibelius's Symphony No. 8 was his final major compositional project, occupying him intermittently from the mid-1920s until around 1938, though he never published it. During this time Sibelius was at the peak of his fame, a national figure in his native Finland and a composer of international stature. A fair copy of at least the first movement was made, but how much of the Eighth Symphony was completed is unknown. Sibelius repeatedly refused to release it for performance, though he continued to assert that he was working on it even after he had, according to later reports from his family, burned the score and associated material, probably in 1945.
Document 5: Niccolò Paganini: Niccolò (or Nicolò) Paganini (] ; 27 October 178227 May 1840) was an Italian violinist, violist, guitarist, and composer. He was the most celebrated violin virtuoso of his time, and left his mark as one of the pillars of modern violin technique. His 24 Caprices for Solo Violin Op. 1 are among the best known of his compositions, and have served as an inspiration for many prominent composers.
Document 6: List of compositions by Jean Sibelius: The following is a complete list of the orchestral and chamber works of the Finnish composer Jean Sibelius, as well as an incomplete list of works for solo piano, chorus, and voice. Primarily known for his compositions for orchestra, the core of Sibelius's oeuvre is his set of seven symphonies, the Violin Concerto, and a number of tone poems, in particular "En saga", "Lemminkäinen" (which includes "The Swan of Tuonela"), "Finlandia", "Pohjola's Daughter", "The Oceanides", and "Tapiola". In addition, works such as the "Karelia Suite", "Valse triste", "Kullervo", "Luonnotar", "Pelléas et Mélisande", "The Tempest", and the String Quartet in D minor, "Voces intimae" have found favor with the public.
Document 7: Leevi Madetoja: Leevi Antti Madetoja (] ; 17 February 1887, Oulu – 6 October 1947, Helsinki) was a Finnish composer, music critic, conductor, and teacher of the late-Romantic and early-modern periods; he is generally considered to be among the most significant Finnish composers to emerge after Jean Sibelius, under whom he studied privately from 1908–10. The core of Madetoja's oeuvre consists of a set of three symphonies (1916, 1918, and 1926), arguably the finest early-twentieth century additions to the Finnish canon of any composer, Sibelius excepted. As central to Madetoja's legacy is his opera, "The Ostrobothnians" (1924), dubbed Finland's "national opera" following its successful premiere and, even today, a stalwart of its repertoire. Madetoja's other notable works include an "Elegia" for strings (1909); "The Garden of Death" (1918–21), a three-movement suite for solo piano; the "Japanisme" ballet-pantomime, "Okon Fuoko" (1927); and, a second opera, "Juha" (1935).
Document 8: Symphonic Odysseys: Symphonic Odysseys: Tribute to Nobuo Uematsu was a symphonic tribute concert held in Cologne, Germany on July 9, 2011 at the Cologne Philharmonic Hall. The concert exclusively paid homage to the work of Japanese composer Nobuo Uematsu and featured music selected from his works as a video game music composer. Among the games featured were "Lost Odyssey", "Blue Dragon", "Last Story", "King's Knight", "Chrono Trigger", "Final Fantasy Legend", and selected works from the "Final Fantasy" series. The concert was produced and directed by Thomas Böcker, with arrangements provided by Finnish composer and musician Jonne Valtonen, along with Roger Wanamo, Masashi Hamauzu, and Jani Laaksonen. The concert was performed by the WDR Rundfunkorchester Köln and the WDR Radio Choir Cologne under conduction from Arnie Roth, with guest performers Benyamin Nuss and Juraj Čižmarovič joining the orchestra. A video recording of "Symphonic Odysseys" was streamed live online.

He conducted three major US orchestras – in Nashville, Tennessee, Des Moines, Iowa, and Jacksonville, Florida. He was also the associate conductor in Buffalo, New York, where he conducted three quarters of all concerts and has been guest conductor for several orchestras including the Boston Pops Orchestra (seven times), Denver, St Louis, Rochester, Hartford, Muncie, Yomiuri, Toronto and Jerusalem. He was the first US conductor of a major Japanese symphony orchestra, the Yomiuri Nippon Symphony Orchestra. He was the first conductor to hire black musicians in a classical orchestra in the USA.
Document 10: Aube (musician): Akifumi Nakajima (中嶋昭文 , Nakajima Akifumi ) (January 13, 1959 – September 25, 2013), better known by his stage name Aube, was a Japanese noise musician. He had released many CDs, LPs and cassettes since 1991, and was regarded as one of the most important noise musicians working of his time. He did not like to term his work "music," preferring the term "design": "I don't think of myself as a musician or an artist. I'm a designer. I therefore consider my sound works to be designs as well". The essential element of his Aube project was that each record was composed with only a single material source, manipulated and processed using various types of electronic equipment. Examples of sources he manipulated include water, fluorescent lamps, voltage-controlled oscillators, voices, pulmonary sounds, the Holy Bible's pages and sounds made with steel wire.
Document 11: Edvard Grieg: Edvard Hagerup Grieg (] ; 15 June 18434 September 1907) was a Norwegian composer and pianist. He is widely considered one of the leading Romantic era composers, and his music is part of the standard classical repertoire worldwide. His use and development of Norwegian folk music in his own compositions put the music of Norway in the international spectrum, as well as helping to develop a national identity, much as Jean Sibelius and Antonín Dvořák did in Finland and Bohemia, respectively.
Document 12: Kullervo (Sibelius): Kullervo, Op. 7, is a suite of symphonic movements by the Finnish composer Jean Sibelius. Although often referred to as a "choral symphony," the work avoids traditional symphonic structure and its five movements constitute a set of related but independent tone poems. The third and fifth movements make use of a men's chorus. The third, authorized by the composer for performance as an independent work, also calls for two soloists, a baritone and a mezzo-soprano. Based on the character of Kullervo in the epic poem "Kalevala" and using texts from that poem, the work premiered to critical acclaim on 28 April 1892 with Emmy Achté and Abraham Ojanperä as soloists and the composer conducting the chorus and orchestra of the Helsinki Orchestra Society, which was founded in that year.
