Bedřich Smetana

Smetana often refers to the Czech composer Bedřich Smetana.
   is a '"festival opera" in three acts, with music by Bedřich Smetana.
 The libretto was originally written in German by Josef Wenzig, and was then translated into Czech by Ervin Špindler.
 In Czech historical myth, Libuše, the title character, prophesied the founding of Prague.
 The opera was composed in 1871–72 for the coronation of Franz Josef as Czech king.
 This did not happen and Smetana saved "Libuše" for the opening of the National Theatre in Prague, which took place nine years later on 11 June 1881.
 After the destruction of the National Theatre in a fire, the same opera opened the reconstructed theatre in 1883.
 The first US performance was reported to have occurred March 1986, in a concert version at Carnegie Hall with Eve Queler and the Opera Orchestra of New York.
Oscar Peterson Plays George Gershwin is a 1952 album by pianist Oscar Peterson of popular songs written by George Gershwin and Ira Gershwin.

Antonín Leopold Dvořák ( ; ] ; 8 September 1841 – 1 May 1904) was a Czech composer.
 After Bedřich Smetana, he was the second Czech composer to achieve worldwide recognition.
 Following Smetana's nationalist example, Dvořák frequently employed aspects, specifically rhythms, of the folk music of Moravia and his native Bohemia.
 Dvořák's own style has been described as "the fullest recreation of a national idiom with that of the symphonic tradition, absorbing folk influences and finding effective ways of using them."

Bedřich Smetana (] ; 2 March 1824 – 12 May 1884) was a Czech composer who pioneered the development of a musical style which became closely identified with his country's aspirations to independent statehood.
 He is thus widely regarded in his homeland as the father of Czech music.
 Internationally he is best known for his opera "The Bartered Bride" and for the symphonic cycle "Má vlast" ("My Homeland"), which portrays the history, legends and landscape of the composer's native land.
