Just did our first show last night since pre-pandemic. Wedding that had been scheduled for over a year and postponed twice. Varying levels of comfort within the 8 piece band. Masks were required indoors; exceptions made for horn players. I used a simpler "sleeve" type of stretchy cover over my nose/mouth/neck that made it easier to sing (at least I felt it did). Also didn't interfere with my in-ear monitors.
We all have our own mics. Hand sanitizer was plentiful. I was at the very back of the stage in nobody's exhale zone. We had good distancing from each other, and excellent separation from the crowd. A room that holds 400 was set up for perhaps 150. I'm not saying we were at zero risk, but it could have been a LOT worse. I sure didn't eat the dinner that was being served in a buffet line, or the desserts that sat uncovered for up to 7 hours. I stayed outdoors on breaks, which also kind of sucked due to 90F and humidity.
For me, playing was not fun. It was work. Two outdoor rehearsals were supposed to knock off the rust, but we were nowhere near tight enough for my liking. Plus, the masks greatly inhibit on-stage communication. Already we can't hear each other talk, so it's eye contact, facial expression, lip-reading... Just about impossible with face coverings.
Most of all, I was disappointed with how the post-covid challenges sucked the joy right out of the gig.
Best of luck to those getting back on stage!
