Context_1 : Nikolay Figner (18571918), lyric tenor, and Medea Figner (18591952), mezzo-soprano, later soprano, were a husband-and-wife team of opera singers active in Russia between 1889 and 1904. Medea was Italian-born (her original surname was Mei) but she became completely Russianized after marrying Nikolay. They had separate careers before their wedding, and again after their divorce in 1904, but during the 15 years of their marriage they almost always sang in the same performances. They created the main tenor and soprano roles in two operas by Pyotr Ilyich Tchaikovsky "The Queen of Spades" and "Iolanta" and appeared in a number of other important Russian musical premieres. Context_2 : Iolanta, Op. 69, (Russian: ) is a lyric opera in one act by Pyotr Tchaikovsky. It was the last opera he composed. The libretto was written by the composer's brother Modest Tchaikovsky, and is based on the Danish play "Kong Renes Datter " ("King Rene's Daughter") by Henrik Hertz, a romanticised account of the life of Yolande de Bar. In the original Danish play, the spelling of the princess's name was "Iolanthe", later adopted for the otherwise unrelated Gilbert and Sullivan operetta of that name. The play was translated by Fyodor Miller and adapted by Vladimir Zotov. The opera received its premiere on 18 December 1892 in Saint Petersburg. Context_3 : Kong Renes Datter ("King Rene's Daughter") is a Danish verse drama written in 1845 by Henrik Hertz. It is a fictional account of the early life of Yolande of Lorraine, daughter of Rene of Anjou, in which she is depicted as a beautiful blind sixteen-year-old princess who lives in a protected garden paradise. The play was highly popular in the 19th century. It was translated into many languages, copied, parodied and adapted. The Russian adaptation by Vladimir Zotov was used as the basis for the 1892 opera "Iolanta", written by Tchaikovsky, with libretto by his brother Modest Ilyich Tchaikovsky.

Context_5 : British composer Michael Tippett composed his Concerto for Piano and Orchestra between 1953 and 1955 on a commission from the City of Birmingham Symphony Orchestra. The overall character of the work was influenced by the composer's hearing German pianist Walter Gieseking rehearse Ludwig van Beethoven's Fourth Piano Concerto in 1950. Its musical content, while influenced by this concerto, was also shaped largely by Tippett's opera "The Midsummer Marriage", which he had completed in 1952. While Tippett had conceived the work initially in the mid-1940s, he had been preoccupied in much of the intervening time with "The Midsummer Marriage". Context_6 : Anna Nechaeva is Russian soprano singer who was born in Saratov and used attend its Conservatory in 1996.
