"We do big events really well here in the city of Philadelphia," Gillison said.
Like last year's inaugural event, Jay Z curated this year's lineup and included artists from many different genres. His wife, Beyonce, will headline today's show, which also features Deadmau5, Public Enemy and Empire of the Sun. Nine Inch Nails has top billing tomorrow, following Queens of the Stone Age, Wiz Khalifa and Macklemore & Ryan Lewis.
The city will be reimbursed for all excess police, fire and medical costs, Gillison said. LiveNation, which organized the event, has already submitted a $200,000 down payment on those expenses, which could reach about $500,000.
"I wish all of the big events paid like these guys," Gillison said. "These guys have been great to work with."
Gillison cautioned attendees against bringing unnecessary bags - especially opaque ones - because security will need to examine them. He said the city has learned a few lessons since last year, including some from the Boston Marathon bombing this spring.
There are new cameras along the Parkway, he said, and there will be bomb-sniffing dogs at the show.
City Representative Desiree Peterkin-Bell said Made in America is helping to make Philly a livelier place during the once-sleepy Labor Day weekend.
"Folks usually run away from the city, but this year folks are coming to the city," she said, noting that hotels have seen increased bookings.
The city expects a $10 million overall economic impact from the event.
