Krzysztof Penderecki (born November 23, 1933 in D?bica) is a Polish composer and conductor. His 1960 avant-garde Threnody to the Victims of Hiroshima for string orchestra brought him to international attention, and this success was followed by acclaim for his choral St. Luke Passion. Both these works exhibit novel compositional techniques. Since the 1970s Penderecki's style has changed to encompass a post-Romantic idiom.
Georg Philipp Telemann (14th March 1681–25th June 1767) was a German Baroque composer, born in Magdeburg. Self-taught in music, he studied law at the University of Leipzig. The most prolific composer of his era, he was a contemporary of Johann Sebastian Bach and a life-long friend of Georg Friedrich Händel. While in the present day Bach is generally thought of as the greater composer, Telemann was more widely renowned for his musical abilities during his lifetime.
Conlon Nancarrow (b. October 27, 1912, Texarkana - d. August 10, 1997, Mexico City) was an American-born composer who lived most of his life in Mexico. Nancarrow is remembered almost exclusively for the pieces he wrote for the player piano. He was one of the first composers to use musical instruments as mechanical machines, utilising their capacity to play complex polyrhythms at tempos far beyond human performance ability.
