For those staying at home and lying low, the Metropolitan Opera in New York has announced a full schedule of nightly streaming operas, all free:
Met Opera Homepage
All “Nightly Met Opera Streams” will begin at 7:30pm EDT and will remain available via the homepage of metopera.org for 20 hours. The homepage link will open the performance on the Met Opera on Demand streaming service. The performance will also be viewable on all Met Opera on Demand apps."
It's free but I have no idea if you have to register to stream or not.
