When I was younger I was in a rock band, plus it was absolutely a fantastic experience, and the only concern I ever absolutely had being in a rock band was with the locations the two of us toured in, there was never any AC! It would be okay with me if there was no A/C in the lavatorys or something, but the concern was there was no A/C anywhere in sight! Our tour bus was pretty old, so there was no working air conditioner inside, but i would say about half of the locations the two of us went to were outside or simply had no working HVAC system.
In the Wintertide it was okay to not have AC, or even a easy working gas furnace for that matter but in the Summer it was not okay.
I don’t suppose if you have ever jumped around for hours in a room with hundreds of people plus no HVAC, but it is not fun. Once our show was over the two of us would be drenched in sweat plus have to retire to our tour bus with no AC, it was absolutely a lot to go days separate from A/C at some points, then my number one area about returning home would always be to go see my parents because there HVAC plan was so nice. I suppose it might seem silly that I enjoyed HVAC so much, but it absolutely makes a pressing difference in comfort. It got to the point where I started reading articles about how to service HVAC so that whenever the two of us were at a location with no A/C I would be able to at least look at their plan plus see if it was fixable.
