When the performers are out there under the lights, in front of the crowd, it can get hot.
I work for the facility, not with any a single unique band or artist, but my task is particularly important, but rock bands absolutely have it the worst, because they are so high-energy on stage, & have the brightest lights.
Stage plays are much different, & a lot calmer, but they also rely more on heavy period makeup, which can run if the actors get too hot. I am the head Heating, Ventilation and A/C tech for the facility, & I work hard to make sure the audience & the performers all get the best possible experience. I don’t do it alone, of course, because the gargantuan size of our temperature control method requires a full team of certified experts. If you have never before seen an industrial sized Heating, Ventilation and A/C system, you might just get blown away by the size of these things. The scope is enormous! You know how large your own Heating, Ventilation and A/C method is at home, & how it is strong enough to cool or heat your entire house; Now picture a apartment a single hundred times as big, holding thoUnited Statesnds of people a night, & consider how big that Heating, Ventilation and A/C method needs to be! This is how I make my residing, spending all morning every morning tending to the behemoth heating & cooling system, with its miles worth of HVAC duct. That’s right, our method has over several miles worth of HVAC ducts, & I have to make sure every last inch of it is in perfect laboring condition.
