Question: In what country was Alfred Schnittke's Nagasaki given its public premiere?
Context: Research Centre for Russian Music (CRM) is a research centre based at Goldsmiths, University of London.  The main purpose of the centre is to promote research, publication and performance.  It offers interdisciplinary activities focused on cultural, social, political and musical problems of Russian modern history and based on its archival collections.  The CRM works in collaboration with the Serge Prokofiev Archive and the Alfred Schnittke Archive which contains manuscripts, facsimiles of all scores (including unfinished ones), private papers, sketches, photos, films, tapes of Schnittke's own performances and talks, all published scores, books and articles on Schnittke, and all existing recordings of his music. Kronos Quartet Performs Alfred Schnittke: The Complete String Quartets Russian composer Alfred Schnittke wrote his Symphony No. 2, subtitled "St. Florian" and "Invisible Mass" in 1979.  It is a choral symphony, written for contralto, countertenor, tenor and bass, plus chorus and orchestra.  The symphony was written in homage to 19th century Austrian composer and organist Anton Bruckner, who was closely associated with St. Florian's Priory in the town of Sankt Florian, Upper Austria, and who is buried under the organ there. Cape Town (Afrikaans: Kaapstad) is a coastal city in South Africa.  It is the second-most populous urban area in South Africa after Johannesburg.  It is also the capital and primate city of the Western Cape province. The Concerto Grosso No. 1 was the first of six concerti grossi by Soviet composer Alfred Schnittke.  It was written in 1976-1977 at the request of Gidon Kremer and Tatiana Grindenko who were also the violin soloists at its premiere on 21 March 1977 in Leningrad together with Yuri Smirnov on keyboard instruments and the Leningrad Chamber Orchestra under Eri Klas.  It is one of the best-known of Schnittke’s polystilistic compositions and marked his break-through in the West. Alfred Schnittke (Russian: Альфре́д Га́рриевич Шни́тке , Alfred Garrievich Shnitke; November 24, 1934August 3, 1998) was a Soviet and German composer.  Schnittke's early music shows the strong influence of Dmitri Shostakovich.  He developed a polystylistic technique in works such as the epic Symphony No. 1 (1969–1972) and his first concerto grosso (1977).  In the 1980s, Schnittke's music began to become more widely known abroad with the publication of his second (1980) and third (1983) string quartets and the String Trio (1985); the ballet "Peer Gynt" (1985–1987); the third (1981), fourth (1984), and fifth (1988) symphonies; and the viola (1985) and first cello (1985–1986) concertos.  As his health deteriorated, Schnittke's music started to abandon much of the extroversion of his polystylism and retreated into a more withdrawn, bleak style. Winter Was Hard is a studio album by the Kronos Quartet.  It contains compositions by Aulis Sallinen, Terry Riley, Arvo Pärt, Anton Webern, John Zorn, John Lurie, Ástor Piazzolla, Alfred Schnittke, and Samuel Barber. Historia von D. Johann Fausten is an opera by the Russian composer Alfred Schnittke (1934-1998) in three acts, with introduction and epilogue to the German libretto by Jörg Morgener (Jürgen Köchel) and Alfred Schnittke after the anonymous prose book of the same name (published by Johannes Spies in 1587). Nagasaki is an oratorio composed by Soviet composer Alfred Schnittke in 1958, at the age of 25.  It was Schnittke's graduation composition in the Moscow Conservatory, and the topic was suggested by his teacher Evgeny Golubev.  The work was considered formalistic, and Schnittke was accused of "forgetting the principles of Realism in music".  Thus, he suppressed the expressionistic central movement depicting the nuclear explosion and modified the finale.  It was recorded by the Moscow Radio Symphony in 1959 and broadcast to Japan through Voice of Russia, but it wasn't printed and it didn't receive any subsequent performances.  Nagasaki was finally given its public premiere in its original form in Cape Town on 23 November 2006, eight years after Schnittke's death, by Hanneli Rupert and the Cape Philharmonic conducted by Owain Arwel Hughes. Symphony No. 9 by Alfred Schnittke was written two years before his death in 1998.  The reconstruction of the manuscript of a barely readable score was made by a younger generation composer – Alexander Raskatov – hired by Irina Schnittke, the composer's widow.  Raskatov not only reconstructed Schnittke’s Ninth but also wrote his own composition: "Nunc dimittis – In memoriam Alfred Schnittke".  The premiere recording of both pieces was conducted by Dennis Russell Davies.
