Leo Ornstein was an American experimental composer and pianist born as Lev Ornshteyn on 11 December 1895 in Kremenchug, Russian Empire. He achieved professional recognition for a musical style characterized by futurism and the early use of tone clusters. Ornstein studied at the Imperial School of Music in Kiev and the St. Petersburg Conservatory before his family emigrated to the United States in 1906. He attended the Institute of Musical Art and made his New York debut in 1911. His recording career includes solo piano pieces such as âWild Men's Danceâ (1913), âImpressions of the Thamesâ (1913), and âSuicide in an Airplaneâ (1918). After withdrawing from public performance in the early 1930s, he established the Ornstein School of Music and continued to compose, completing the Eighth Piano Sonata (1990). Ornstein died on 24 February 2002 in Green Bay, Wisconsin.
