No stranger to controversy these days The Bayreuth Festival opened at the end of July with a new production of Lohengrin directed by one of the best-known Regietheater directors, Hans Neuenfels. His tongue-in-cheek take on Richard Wagner's most romantic opera involved setting it in a land overrun by rats. There was laughter at the Festspielhaus and there were loud boos as well.  Ultimately, over the years, the production became one of the most popular at the Green Hill.  I was very lucky to see it in the summer of 2012.  That first summer, though, Jonas Kaufmann played the title role. Soprano Annette Dasch, along with Kaufmann, ignited opening night with their passionate singing.  She stayed with the production throughout its run.
