Two composers who helped Daniel Barenboïm to make a name for himself as pianist and orchestra director, are Mozart and Beethoven. In the 1980s, while he was at the peak of his career, he undertook a recording project of the last eight concertos for piano by Mozart with one of the greatest German orchestras, the Berliner Philharmoniker. These performances were recorded in the neoclassic frame of the Siemens-Villa in Berlin, which takes its name from the famous patron and music lover Ferdinand Werner Siemens. These movies represent an extraordinary memory of the main interpretation existing at that time of these Concertos for piano by Mozart, considered as real masterpieces.
There is no certainty about the date of composition of this last concerto. The manuscript says "January 5, 1791" (id est eleven months before the composer's death, a year where Die Zauberflöte, the Clarinet concerto or the Requiem were born); but the essayists have discussed this several times, supposing the work belonged to the years 1788-1789. Anyways, it was written a few years after the 26th concerto. Its style slightly differs from the other ones' (notably because of its thin orchestra and the impression of peace it gives). The work around the themes announces the music of the 19th century.
