The Metropolitan Opera is growing mould

From one of our moles inside the Metropolitan Opera:

Back in August, the Tannhauser set, which had been in storage for roughly eight years, was brought into the Met in preparation for this season.

Cases were opened and mold nearly knocked some of the guys over. Black mold.

Some “heads” from scenic were brought in to take a look; they suggested a thorough cleaning/ disinfecting with a subpar product and pack it up for later.

This Wednesday, November 15, the cases were opened up and said mold on the Tannhauser ground cloth, had grown to toxic levels.
The crew were responsible for opening cases uo. Some became ill. The ground cloth was deemed a complete hazard and trashed.

The chorus and soloists were scheduled to have their first staging rehearsal a few hours later on this set. The air was full of mold and other particles that are dangerous for some people.

Rehearsal went on as planned without a ground cloth.

Health and safety?
