The musical language of the New York-based Arnold Rosner (1945–2013) had its roots in the modal harmony and rhythm of pre-Baroque polyphony and evolved in an array of unusual directions, producing a style that is instantly recognizable and immediately appealing – as can be heard in the three works on this recording. Rosner’s Nocturne suggests the immensity – and the implacable violence – of outer space, whereas his overture Tempus Perfectum has its starting point in Renaissance dance. The monumental Sixth Symphony opens with music of volcanic ferocity and vehemence; the central Adagio then provides an island of troubled calm before the dignified opening of the finale presages a symphonic Allegro of wild, freewheeling energy; only when its immense force is spent does this powerful masterpiece sink to an uneasy close.
