This is not only Mahler's longest symphony, it is also the longest in the entire symphony repertoire. In addition, it requires a large cast including contralto soloist, ladies choir, children's choir and a very large orchestra. Ironically, Mahler himself called it his "monster symphony". The symphony depicts nature in the broadest sense and the six movements indicate the story of Creation when God created the world in six days. The orchestral movement is full of variety, containing everything from magnificent march and exquisitely beautiful nocturne to innocent choir of angels. Mahler obtained the words from Friedrich Nietzsche and from the collection of German songs called Des Knaben Wunderhorn. Conductor, Patrik Ringborg, returns after having successfully unfurled the German orchestral splendour of Salome in 2011.
