Mostly that it is really stupid to travel across the country to a hot spot for a gig right now. I know several people who have died from COVID, including a 20 year old...one person I know under 30 with it is currently in the hospital. It's not something to be played with. They're needlessly putting themselves and their families at risk - you can take all the precautions you want and still get it, because they aren't foolproof.
And on the off chance that this was a corporate gig or some rich guy who loves ITM buying a gig and getting to hear these songs first while the rest of us languish (though I agree that a corporate gig seems unlikely - I do think it probably was recorded for future distribution or streaming)...that would really hurt.
