Question: Leff Nicolas Pouishnoff played works by which Austrian composer born on January 31, 1979?
Context: Clotilde Kainerstorfer (2 July 1833 – 26 September 1897) was an Austrian composer born in Hall in Tirol.  She composed sacred works and published ten pieces for piano and organ in Augsburg in 1878 as her first known compositions.  She died in 1897 in Linz. Franz Peter Schubert (] ; 31 January 179719 November 1828) was an Austrian composer. Anna Pessiak-Schmerling (1834 – 14 March 1896) was an Austrian composer born in Vienna. Leff Nicolas Pouishnoff (Russian: Лев Николаевич Пышнов, "Lev Nikolayevich Pyshnov") (11 October [O.S. 29 September] 1891 28 May 1959) was a Ukrainian-born pianist and composer, who made his home in the United Kingdom and whose career was largely in the West, from the 1920s onwards.  He was especially associated with performances of the works of Frédéric Chopin, though he also played works by Franz Schubert, Robert Schumann, and Franz Liszt.  His was among the earliest recordings of Schubert's Sonata in G major, D 894, made for English Columbia around 1928. Janus Plousiadenos (~1429-1500) was a 15th-century Greek Renaissance scholar, hymnographer and composer born in Crete.  Plousiadenos was in favor of the Union of the Orthodox and Catholic Churches and wrote extensively on the subject.  The 1455 "Defensio synodi Florentinae", often misattributed to Gennadius Scholarius is in fact his work.  Plousiadenos was also an avid composer and hymnographer and dedicated several of his works to his friend and fellow Greek scholar Cardinal Bessarion.  His sacred compositions for the Orthodox church use a discantus technique, thus achieving a polyphonic texture, a practice that underlines the innovative character of his works in regard to the usually considered as monophonic "byzantine chant" just before the fall of the Eastern Roman Empire. Renate Spitzner (born 28 May 1943 in Prague, Czech Republic) is an Austrian composer (member of the "OeGZM" – Austrian Society of contemporary music), musician, music pedagogue, music therapist and founder of the "Music-social Method" – "Musisch-soziale Methode".  Spitzner studied violin, organ, piano, trumpet, music education and music therapy.  She absolved the University of Music at Vienna.  At her work at the psychiatric hospital "Baumgartnerhöhe" in Vienna, Austria, she developed the "Music-social Method" in which patients and professional musician play together.  For that common play-together music pieces of the classic period are specially adapted or also new composed.  First time the "Music-social method" has been recognized and approved at the "United Nations Decade of Disabled Persons 1983–1992".  Spitzner is the mother of the Austrian composer Gerald Spitzner. Johannes Kretz (born 8 May 1968 in Vienna) is an Austrian composer and teacher for computer music and music theory.  He lives and works in Vienna and created various compositions in the fields of new music, among those: music theatre, orchestra works, chamber music, sacred music and works with electronics.  He won an Austrian State Prize for music in 2004. Fred Onovwerosuoke (born 1960) is an American composer born in Ghana of Nigerian parents.  He is a multiple winner of the ASCAP Award, among other awards such as the America Music Center Award, Brannen-Cooper Fund Award, and the Minnesota Orchestra Honorable Mention.  “FredO,” as he is called by friends and colleagues was born in Secondi-Takoradi, near the Atlantic Coast in Ghana, West Africa.  Early childhood and education through college years were spent in both Ghana and Nigeria.  In 1990, he attended Principia College, Elsah, Illinois, on a full scholarship, and while there studied music theory and 20th Century composition techniques under Jim Dowcett, as well as Engineering Science and Computer programming with David Cornell and Tom Fuller.  Although Onovwerosuoke has had a wide-ranging training that spans composition, electrical and electronic engineering, information technology, management and musicology, he is known to attribute his interest in music to his childhood as boy-soprano and to his high-school music teacher, Sam Anyanele, who instilled him a deep love of indigenous African music.  His tutelage under Dowcett at Principia was said to unleash a creative individualism that eventually evolved into a career as a composer with works that bear influences from Africa, the Caribbean and the American Deep South. Franz Schubert (31 January 1797 – 19 November 1828) was an extremely prolific Austrian composer.  He composed some 1500 works (or, when collections, cycles and variants are grouped, some thousand compositions).  The largest group are the lieder for piano and solo voice (over six hundred), and nearly as many piano pieces.  Schubert also composed some 150 part songs, some 40 liturgical compositions (including several masses) and around 20 stage works like operas and incidental music.  His orchestral output includes a dozen symphonies (seven completed) and several overtures. Schubert's chamber music includes over 20 string quartets, and several quintets, trios and duos. Michael Kibbe (born 1945) is an American contemporary classical music composer born in San Diego, California.  He has composed over 240 concert works and created numerous arrangements.  His writing covers many musical styles, encompassing tonal, modal and non-diatonic languages.  His style often incorporates modern structures but is still accessible to the popular classical listener.  Some of his works come right of the Romantic Era yet his style in some writings has been compared to Prokofiev.  There are influences of American composer Gershwin in the Serenade Number 2 for two clarinets that seem at once blues, jazz and classical.  His music can often reflect themes that bring to mind different cultures.
