The show is a co-production with Aix-en-Provence, where the New York Times headline said it had been reimagined in a ‘violent, racist world’ (though its critic wished the director had gone further).
Edinburgh first circulated the glowing review to prospective ticket buyers, then got cold feet.
It has now alerted patrons that the opera contains ‘adult scenes’ that would be ‘totally unsuitable for children’.
A spokeswoman said: ‘We don’t want to offend anyone. If somebody has bought a ticket, doesn’t think the show will be suitable for them and doesn’t want to come then we will obviously try to help them.’
