We're probably going to be much more cautious in the US, given the situation here.

My orchestra has not officially canceled anything yet; officially we are still resuming normal rehearsals in our usual venue in late August.

HOWEVER... it appears unlikely that will actually happen. Orchestra management is currently exploring alternate options, all of which involve rehearsing and performing outdoors. I don't think playing indoors is even being considered now. Depending on both the coronavirus situation and the availability of appropriate venues, we may decide to perform as a full orchestra outdoors (appears unlikely), split into a string orchestra and a wind band for the fall, or organize an outdoor chamber music series. Also depending on venue, we would either play in front of a socially distanced audience or produce livestream-only concerts. An email went out to orchestra members asking for venue suggestions for both outdoor rehearsals and outdoor concerts that would allow musicians to be safely distanced.

My orchestra is back, more or less. (I'm still not rehearsing due to injury.) Rehearsing outdoors, strings orchestra only, masked and distanced.

The first concert of the season was supposed to be last night; obviously it didn't happen. The new concert program is set, but the concert date is still up in the air because the start of rehearsals was delayed by wildfire smoke, and because we're still trying to find an appropriate outdoor performance venue. For selfish reasons I don't mind the delay at all, because it gives me a decent chance of returning in time to rehearse adequately and play the concert.

Just to assure people we're still around, the orchestra released short video clips from the first two rehearsals.

Again, I'm not involved so far, but still hoping to recover from my car accident in time to perform.
