What is "regieoper"

Regieoper (German for director's opera) is a form of Regietheater specific to opera. In Regieoper, the stage director assumes a central role in determining the concept of an opera, often exchanging the established traditions related to that opera for an approach that may or may not adhere to the composer's or librettist's original intention. The director's approach may include but is not limited to changing the staging intended by the composer or librettist, modernizing the story to reflect contemporary political controversies, and infusing the production with shock value (most often, sexuality).
