Oh my, that's got to be awful. I don't consider myself the same calibre as you as a stage pianist -- composition, arranging, and teaching were always more my speed. They're far less scary and demanding than performing. I'm OK singing in public but my stage presence leaves much to be desired. Even if I was a better performer, there is no performance scene these days, and it was rough trying to make a living in Chicago doing music before the Plandemic. So many of my musician and actor friends have fallen on hard times and cannot support themselves. I'm not even having an easy time getting new students. I suspect that I'm being snubbed because I'm fairly open about being unvaccinated.

Vaccinated or not, it's horrible out there for performing musicians right now. A friend of mine from musical college is drinking himself to death. He has two children.

If I had a large enough house, I would host house concerts for solo musicians and small bands. Basically you go around on mini-tours around the suburbs and small, intimate audiences flock around you in private houses. Kind of like a cooking circle but for performing musicians.
Everyone who attends pays a modest fee and it all goes to the musician. If there's any way you can appeal to a wealthy patron of the arts in your area to do house concerts, I honestly think that would be your best bet.
