Context paragraphs:
Kamarinskaya: 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.

Paul Hindemith: Paul Hindemith ( ) (16 November 1895 – 28 December 1963) was a prolific German composer, violist, violinist, teacher and conductor.  Notable compositions include his song cycle "Das Marienleben" (1923), "Der Schwanendreher" for viola and orchestra (1935), and opera "Mathis der Maler" (1938).  Hindemith's most popular work, both on record and in the concert hall, is likely the "Symphonic Metamorphosis of Themes by Carl Maria von Weber", written in 1943.

Tzofei Tel Aviv: Tzofei Tel Aviv (or Tel Aviv Scouts in English) is a musical group originating from Israel.  The performers are teenagers, picked out of the Israel Scouts in Tel-Aviv, Israel.  They tour around the world, performing mostly Hebrew songs for Jewish organizations and others the world over.  For example, they performed Yom Ha'atzmaut concerts in Lima and Guayaquil in June 2003, as they did in St. Louis Park, MN, in 2006.  The group's musical director is Moishele Yosef, who has various other jobs in the musical profession.

The Great Glinka: 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.

Hindemith Prize: The international Paul Hindemith Prize promotes outstanding contemporary composers within the framework of the Schleswig-Holstein Music Festival (SHMF).  The award commemorates the musical pedagogy of Paul Hindemith, who wrote the composition "Plöner Musiktag" in 1932 on behalf of the Staatliche Bildungsanstalt Plön.  The music prize is endowed with 20,000 € and goes together with a composition commission.  The prize is presented annually by the Hindemith Foundation in Blonay (Switzerland), the Walter and Käthe Busche Foundation, the Rudolf and Erika Koch Foundation, the Gerhard Trede Foundation, the Franz Wirth Memorial Trust and the Cultural Office of the Free and Hanseatic City of Hamburg since 1990.  Since 2010, the winner is found partly by a composition competition.  The work of the prize winner is to be premiered within the framework of the Schleswig-Holstein Music Festival.

Mikhail Glinka: 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.

Mily Balakirev: Mily Alexeyevich Balakirev (Russian: Ми́лий Алексе́евич Бала́кирев , ] ; 2 January 1837  – 29 May [O.S. 16 May] 1910 ) was a Russian pianist, conductor and composer known today primarily for his work promoting musical nationalism and his encouragement of more famous Russian composers, notably Pyotr Ilyich Tchaikovsky.  He began his career as a pivotal figure, extending the fusion of traditional folk music and experimental classical music practices begun by composer Mikhail Glinka.  In the process, Balakirev developed musical patterns that could express overt nationalistic feeling.  After a nervous breakdown and consequential sabbatical, he returned to classical music but did not wield the same level of influence as before.

Nestor Kukolnik: Nestor Vasilievich Kukolnik (Russian: Нестор Васильевич Кукольник ) (1809–1868) was a Russian playwright and prose writer of Carpatho-Rusyn origin.  Immensely popular during the early part of his career, his works were subsequently dismissed as sententious and sentimental.  Today, he is best remembered for having contributed to the libretto of the first Russian opera, "A Life for the Tsar" by Mikhail Glinka.  Glinka also set many of his lyrics to music.

Alexey Verstovsky: Alexey Nikolayevich Verstovsky (Russian: Алексéй Николáевич Верстóвский ) (March 1 [O.S. February 18] 1799 November 17 [O.S. November 5] 1862 ) was a Russian composer, musical bureaucrat and rival of Mikhail Glinka.

A Life for the Tsar: A Life for the Tsar (Russian: Жизнь за царя , "Zhizn' za tsarya"), as it is known in English, although in Soviet times its name was "Ivan Susanin" (Russian: Иван Сусанин ) is a "patriotic-heroic tragic opera" in four acts with an epilogue by Mikhail Glinka.  The original Russian libretto, based on historical events, was written by Nestor Kukolnik, Egor Fyodorovich (von) Rozen, Vladimir Sollogub and Vasily Zhukovsky.  It premiered on 27 November 1836 OS (9 December NS) at the Bolshoi Kamenny Theatre in St. Petersburg.  The historical basis of the plot involves Ivan Susanin, a patriotic hero of the early 17th century who gave his life in the expulsion of the invading Polish army for the newly elected Tsar Mikhail, the first of the Romanov dynasty, elected in 1613.
