Witold Lutosławski

Witold Roman Lutosławski was a Polish composer and conductor. Among the major composers of 20th-century classical music, he is "generally regarded as the most significant Polish composer since Szymanowski, and possibly the greatest Polish composer since Chopin". His compositions—of which he was a notable conductor—include representatives of most traditional genres, aside from opera: symphonies, concertos, orchestral song cycles, other orchestral works, and chamber works. Among his best known works are his four symphonies, the Variations on a Theme by Paganini (1941), the Concerto for Orchestra (1954), and his cello concerto (1970).
