Bavarian State Opera
In July 1998, she sang a for the Richard Wagner Society at the Markgräfliches Opernhaus (Margravial or Margrave's Opera House) in Bayreuth celebrating the 250th anniversary of the house. During the late 1990s, Studer had a period of vocal problems that led to the Bavarian State Opera canceling her contracts in 1998, but after a brief time off the stage, her performances indicated a return to form and the Bavarian State Opera renewed her contract for fourteen more performances.
