Finnish/Swedish composer Moses Pergament (1893-1977).
He was active in almost every conceivable aspect of music during his long career. After having studied the violin in Helsinki and St. Petersburg, he played with the Philharmonic Society in Helsinki. He conducted both choirs and orchestras and was a famed and fearless music critic for the Stockholm newspapers between 1923 and 1965. As a composer, Pergament was dependent on late Romantic as well as modern Expressionistic impulses, but he transformed these to his own tonal language, which is also influenced by Jewish liturgical chant.
