This is what a typical day looks like for Siegel, before and during a show.

“I get in between 7 and 8 a.m., and that’s when we have our first production meeting. After that the band starts coming in. We make sure our hospitality teams are setting up coffee and tea and opening the dressing rooms. I make sure our delivery of portable toilets are coming in, that our turf is clean, and all the leaves and debris from last evening have been blown off.

“Then I check in with the union workers over at the stage. I meet with our production manager, then the front-of-house manager. That’s all in the morning. Then our security deployment arrives and we check them all in, make sure they’re all up-to-date with any threats or anything that we receive from the N.Y.P.D. or Homeland Security.”

This is the time in the day, Siegel said, when they get ready to open the doors to thousands of concertgoers. Then things get frantic.

“There’s a lot of running around. My radio is going off constantly. There was a medical situation last night, so I dealt with that. We tend to have a lot of fainting at shows. Taylor Swift, especially. We had her last week. That was a lot of little girls fainting.

“The best part of my job is knowing that people are coming to us to enjoy their lives, to take a few hours out of their grind. Once a show is up and running and the band is performing and there are smiles on the people’s faces as you’re looking out across them — that, to me, is worth every piece of sweat.” AS TOLD TO GABE COHN
