Lance Ryan also sings Siegfried on the Valencia Ring on DVD/Bluray.
There will also be other cast changes: Endrik Wottrich is leaving Bayreuth for good, he says, and Johan Botha will replace him as Siegmund. Since acting skills are not required in the postcard production by Tancred Dorst, this will be a fine replacement. As mentioned before, Susan Maclean will replace Mihoko Fujimura as Kundry in Stefan Herheim's Parsifal production.
