The mysterious river Traun, which emerges from several springs in the Totes Gebirge (the so-called ‘Dead Mountains’) of Styria (Stiermarken-Austria), flows in full splendor and beauty through the loveliest lakes. The Traun meanders through the Salzkammergut like a crystal ribbon along the Ho llengebirge. This piece is like an exciting musical voyage along the river telling the story of a rich history, from the earliest Celtic settlements to the construction of important power plants. It offers different and versatile passages for all instrument groups, making Mystic River the ideal contest work or the main piece in a challenging concert programme.
