Query: be warned ! avant garde to the point of absurdity !

a cocaine sniffing prince orlofsky . a director who decided to rewrite the operetta putting in new dialogue. dark ,sadistic,amateurish. i knew i was in trouble when i started reading the booklet inside the dvd box. i wish they had put that information on the outside of the box. get the royal opera at covent garden dvd production with placido domingo conducting. one last comment . the costumes were out of some brechtian three penny opera,mother courage german expressionist nightmare.
