Thanks to Harry T. Burleigh and Nathaniel Deft, both early 20th century African-American composers, we have today these glorious arrangements of the spirituals and folk songs. A New Hiding Place is based on the spiritual, "My Lord, what a morning." Juba, paints a landscape of moods and scenes depicting African-American life in the river bottoms of the southern sections of North America. Originally George Gershwin planned to compose twenty-four preludes titled, "The Melting Pot", but his life was tragically cut short and we are left with only a handful. These three preludes were first performed by the composer at the Roosevelt Hotel in New York City in 1926. Each prelude is a well known example of early 20th century American classical music, as influenced by Jazz. Ástor Piazzolla was an Argentine tango composer and a bandoneón player. His oeuvre revolutionized the traditional tango into a new style termed nuevo tango, incorporating elements from jazz and classical music. A virtuoso bandoneónist, he regularly performed his own compositions with different ensembles. Both Radames Gnattali and Camargo Guarnieri are the most important Brazilian composers, after Heritor Villa-Lobos, who influenced the use of folk material to the new generation of nationalist composers, namely Antonio Carlos Join and the boss nova generation, that characterizes today's Brazilian music. Danas Negara is an example of poly-rhythms played throughout in the left hand with a "blues-like" folk melody on top. Negaceando is a choro (it literally means "cry" in Portuguese) which is considered to be the first and most important popular music style typical of Brazil and, despite it's name, this style is often a fast and happy rhythm characterized by the virtuosity and the improvisations of the musician. Garota de Ipanema turned boss nova into a world-wide phenomenon. Boss nova songs left behind the underworld of samba, where people struggled to make a living and shifted to the world of beaches, romance and lazy bohemian life. Blue Rondo a la Turk was inspired on a tour in the Middle East for the U.S. State Department. While walking through the old city of Istanbul en route to a radio show performance, Dave Brubeck heard some street musicians playing a fascinating and complicated rhythm. Soon after he realized that this street rhythm was as familiar to them as the blues in four-four would be to a group of jazz musicians and consequently, this piece emerged from that wonderful walk through Istanbul. Blue Rondo a la Turk is a mix of Turkish rhythms and the blues arranged in the form of a rondo to Mozart's Rondo a la Turca. In 1964 Oscar Peterson wrote and recorded a collection of compositions inspired by towns and regions in his native Canada. The resulting Canadiana Suite travels a musical train ride cross his beloved homeland. It is the first of Peterson's major compositions, one of his best known works, and it was nominated for a Grammy in 1965. The blues and swing themes in these pieces exemplify the contrasts found in Canada's landscape. Rafael Landestoy's escape from his country's dictatorship, in the Dominican Republic, consequently brought him decades of international fame as a pop songwriter, known then as "Bullumba". Having grown tired of the fast and exciting lifestyle, he turned to spiritual inspiration and lived in a monastery for seven years. There he would develop his new music style and signature. These three pieces show both popular rhythms and contemporary sounds with the classics. The two virtuoso etudes are based on George Gershwin songs, Embraceable You and Fascinatin' Rhythm both written in 1924 for the shows, Girl Crazy and Lady be Good. Theses compositions of Earl Wild are most valuable additions to the piano literature and to the transcription of pieces that were originally written for another medium.
