Arnold Schönberg’s Late-Romantic cantata Gurre-Lieder, based on a 14th-century Danish legend, will again be heard at the State Opera in Prague, which hosted its Czech premiere 102 years ago. A colossal apparatus of almost 250 singers and instrumentalists, including the Prague Radio Symphony Orchestra and the Norwegian Radio Orchestra, will appear under the conductor Petr Popelka. Part of the Musica non grata project, the programme will contribute to the celebrations marking the centenary of Czech Radio.
