My main band played at a brewery the other week. There were a couple hundred people there. The band was in the barn where the tap room is. As it is on a large farm, there was plenty of space for people; no crowding. Even when in line for the beer or food, people kept decent spacing and were masked. We play there again in November. Not sure how it will be due to weather - all indoors, or still projecting "out" to the rest of the world.
My other band I splaying a house party next month. Mild concerns all around, but were told we'll be playing in the garage, which will be open if weather permits. That gave us a bit of comfort in accepting the gig.
