From our colleagues at Diapason:
Dijon Opera was at the forefront, the first in France to offer public concerts, from June 17, as part of the Dissonances Chamber Music Series, a festival curated by the violinist David Grimal and the pianist Philippe Cassard. All precautions were taken: of 1,611 seats in the auditorium, only 150 were occupied.
But one case of Covid-19 was diagnosed on June 20 (he is said to be a famous cellist). All further concerts have now been cancelled.
