Boris Godunov - not by Mussorgsky. The story of how Johann Mattheson's political comedy "Boris Goudenow" came into being reads in large parts more exciting than many a mystery script: written in 1710 for the Hamburg Opera at the Gänsemarkt, the work was suddenly withdrawn by the composer. The score fell into oblivion, eventually ended up in the Hamburg City Library, and was long considered lost after World War II. It was not until the end of the 20th century that the opera was tracked down in Armenia and returned to Hamburg, where the premiere finally took place in 2005 after a delay of almost 300 years. The place of action is the Moscow Kremlin. The opera's plot revolves around the story of how the Russian prince Boris Goudenov rises to power through intrigue and becomes Russian tsar.  The new Innsbruck production, under the musical direction of renowned Italian harpsichordist and conductor Andrea Marchiol, makes this baroque gem resound anew.
