A notice on the website for Teatro alla Scala read that the performance was called off due to the strike organized by unions representing the chorus. The new production of Berlioz's piece features choreography by Sasha Waltz and is a co-production between La Scala, Deutsche Oper Berlin and Opéra National de Paris.
The production reportedly has been beset with problems, starting with protests from dancers who said the raked stage was causing them physical pain. Raked stages, which are angled up and away from the audience, are sometimes used in theater and operatic productions for dramatic effect or to allow performers at the back of the stage to be better seen by the audience.
The dancers had threatened to protest, but it remains unclear from published reports if they have walked out of the production. Meanwhile, some of the choristers were upset at having to appear on stage in costume and having to move in time with the music, according to a report in The Guardian.
The British newspaper reports that the choristers who are affected are demanding a bonus, but the management of the company has refused.
It's not known if and when "Romeo and Juliet" will begin performances. The production had been scheduled to run through Jan. 8.
Conlon is due back in Los Angeles in March to conduct Wagner's "The Flying Dutchman" at LA Opera.
