The 75 professional singers of the DNRC are directed by Stefan Parkman, who has conducted most of Sweden's symphony orchestras and several excellent choirs. Probably the least-known of Richard Strauss's (1884-1949) major works are his compositions for unaccompanied chorus--not surprisingly, because only the most accomplished choirs are qualified to perform them. When they are performed, however, the rewards are great: 16 part harmony with antiphonal block passages alternating with intricate polyphony. Six pieces: "Der Abend Op. 34 Nr. 1," "Hymne Op. 34 Nr. 2," Deutsche Motette Op. 62," "Die Cottin im Putzzimmer," and "An den Baum Daphne," featuring the Copenhagen Boys' Choir. This is beautiful, fine, intricate stuff, with soaring harmonies and solos. Extensive liner notes with all lyrics and histories.
