Concerto for Orchestra (Bartók)
The work was written in 1943 and it was first performed on 1 December 1944 in the Boston Symphony Hall by the Boston Symphony Orchestra with the conductor Serge Koussevitzky. It was immediately a great success. Koussevitszky asked Bartók to write this piece. Bartók had just arrived in United States from Hungary. He had to flee because of World War II. Bartók had no money and so he was glad to get some work.
