Anton Bruckner: Josef Anton Bruckner (] ; (1824--)04 1824 (1896--)11 1896 ) was an Austrian composer best known for his symphonies, masses, and motets.  The first are considered emblematic of the final stage of Austro-German Romanticism because of their rich harmonic language, strongly polyphonic character, and considerable length.  Bruckner's compositions helped to define contemporary musical radicalism, owing to their dissonances, unprepared modulations, and roving harmonies.

Georg Solti: Sir Georg Solti, KBE ( ; Budapest, 21 October 1912Antibes, 5 September 1997) was a Hungarian-born orchestral and operatic conductor, best known for his appearances with opera companies in Munich, Frankfurt and London, and as a long-serving music director of the Chicago Symphony Orchestra.  Born in Budapest, he studied there with Béla Bartók, Leó Weiner and Ernő Dohnányi.  In the 1930s, he was a répétiteur at the Hungarian State Opera and worked at the Salzburg Festival for Arturo Toscanini.  His career was interrupted by the rise of the Nazis’ influence on Hungarian politics, and being of Jewish background he fled the increasingly harsh Hungarian anti-Jewish laws in 1938.  After conducting a season of Russian ballet in London at the Royal Opera House he found refuge in Switzerland, where he remained during the Second World War.  Prohibited from conducting there, he earned a living as a pianist.

The premiere was conducted by the composer himself in Saint Petersburg on 8 February 1908.  Its duration is approximately 60 minutes when performed uncut; cut performances can be as short as 35 minutes.

Serafín Estébanez Calderón: Serafín Estébanez Calderón (27 December 1799 – 5 February 1867) was a Spanish author, best known by the pseudonym of El Solitario.  He was born in Málaga.  His first literary effort was "El Listen verde", a poem signed "Safinio" and written to celebrate the revolution of 1820.  He was called to the bar, and settled for some time in Madrid, where he published a volume of verses in 1831 under the assumed name of "El Solitario."  He obtained an exaggerated reputation as an Arabic scholar, and played a minor part in the political movements of his time.  He died in Madrid in 1867.  His most interesting work, "Escenas andaluzas" (1847), is in an affected style, the vocabulary being partly archaic and partly provincial; but, despite its eccentric mannerisms, it is a vivid record of picturesque scenes and local customs.  Estebanez Calderon is also the author of an unfinished history, "De la conquista y pirdida de Portugal" (1883), issued posthumously under the editorship of his nephew, Antonio Canovas del Castillo.

Symphony No. 5 (Bruckner): The Symphony No. 5 in B-flat major (WAB 105) of Anton Bruckner was written in 1875–1876, with minor changes over the next two years.

Dedicated to Karl von Stremayr, education minister in the Austro-Hungarian Empire, the symphony has at times been nicknamed the “Tragic,” the “Church of Faith” or the “Pizzicato”; Bruckner himself referred to it as the “Fantastic” without applying this or any other name formally.
