Rhapsody in Blue is a 1945 fictionalized screen biography of the American composer and musician George Gershwin (September 26, 1898 – July 11, 1937) released by Warner Brothers.
Herbert Elwell (May 10, 1898 – April 17, 1974) was an American composer and music critic.
 A native of Minneapolis, he was among the first Americans to study in France with Nadia Boulanger.
 While in Paris his Quintet for Piano and Strings (1924) garnered more praise than George Gershwin's "Rhapsody in Blue", which was premiered at the same concert.
 He began his studies in music at the University of Minnesota, and went on to work with Ernest Bloch prior to his sojourn in France.
 He also attended the American Academy in Rome during which time he composed his most frequently performed work, the ballet "The Happy Hypocrite" (1925).
Walter Anthony Murphy, Jr. (born December 19, 1952) is an American composer, arranger, pianist, musician, songwriter, and record producer.
 He is best known for the instrumental "A Fifth of Beethoven", a disco adaptation of Beethoven's Fifth Symphony which topped the charts in 1976 and was featured on the "Saturday Night Fever" soundtrack.
 Further classical–disco fusions followed, such as "Flight '76", "Rhapsody in Blue", "Toccata and Funk in 'D' Minor", "Bolero", and "Mostly Mozart", but were not as successful.

Francis Poulenc's Concerto pour deux pianos (Concerto for Two Pianos and Orchestra) in D minor, FP 61, was commissioned by and dedicated to the Princess Edmond de Polignac and composed over the period of three months in the summer of 1932.
 It is often described as the climax of Poulenc's early period.
 The composer wrote to the Belgian musicologist Paul Collaer: "You will see for yourself what an enormous step forward it is from my previous work and that I am really entering my great period."
 Poulenc composed the concerto for the Princess Edmond de Polignac, an American-born arts patron to whom many early 20th-century masterpieces are dedicated, including Stravinsky’s "Renard", Ravel’s "Pavane pour une infante défunte", Kurt Weill’s Second Symphony, and Satie’s "Socrates".
 Her Paris salon was a gathering place for the musical avant-garde.
The Second Rhapsody is a concert piece for orchestra with piano by American composer George Gershwin, written in 1931.
 It is sometimes referred to by its original title, "Rhapsody in Rivets".
Blond Eckbert is an opera by Scottish composer Judith Weir.
 The composer wrote the English-language libretto herself, basing it on the cryptic supernatural short story "Der blonde Eckbert" by the German Romantic writer Ludwig Tieck.
 Weir completed the original two act version of the opera in 1993, making "Blond Eckbert" her third full-length work in the genre.
 Like its predecessors, it was received well by the critics.
 She later produced a one act "pocket" version of the work.
 This uses chamber forces rather than the full orchestra of the two act version and omits the chorus.
 The pocket version receives frequent performances, especially in Germany and Austria, while the full version is available in a recording featuring the original cast.
Rhapsody in Blue is a 1924 musical composition by American composer George Gershwin for solo piano and jazz band, which combines elements of classical music with jazz-influenced effects.
George Jacob Gershwin ( ; September 26, 1898 July 11, 1937) was an American composer and pianist.
