The next webcast of the season from our dear friends at the Bayerische Staatsoper is both at an unusual time, 3:45 PM EDT and an unusual production, Wagner’s Tannhäuser in a controversial new production by Romeo Castellucci. Klaus Florian Vogt will sing the title role; Anja Harteros will perform as Elisabeth. Elena Pankratova is Venus, while Christian Gerhaher is Wolfram von Eschenbach. General Music Director Kirill Petrenko conducts, and you, the cher public, will discuss.
