More than 130 bands performed across on eight stages, including Mumford & Sons, Imagine Dragons, Nine Inch Nails, Phoenix and The Cure. The sold-out concert hosted 100,000 fans each day, and attracted thousands more to other festival-related activities, including 45 official after-parties.
This year, 70 percent of event attendees were from outside Chicago, with 3 percent of all ticketholders being from other countries.
The city is now in its second year of a 10-year agreement with Lolla organizers to host through 2021.
Some street closures remain in effect. Columbus Drive from Monroe to Roosevelt was expected to reopen by Monday at 4 p.m.
But some streets will remain closed as long as cleanup takes -- Balbo from Columbus to Lake Shore Drive will be closed through Thursday at 4 p.m. Jackson from Columbus to Lake Shore Drive will be closed through Wednesday at 4 p.m. Balbo from Michigan Ave. to Columbus will be closed through Wednesday at 4 p.m. Congress Parkway from Michigan to Columbus will be closed through Wednesday at 4 p.m. Jackson from Michigan Avenue to Columbus will be closed through Wednesday at 4 p.m.
The cleanup process can take up to five days of dismantling stages, trucking away that iconic sign and raking up piles of garbage scattered across Grant Park.
"Everything was smooth. The weather was gorgeous, and this was a great, seamless year," said Lindsay Hoffman, marketing manager.
That opinion was echoed by Chicago Police Superintendent Garry McCarthy Monday. He said there was very little crime. But more safety precautions were taken, given the recent closures of U.S. embassies abroad. McCarthy said more undercover officers were in the crowds.
There were a few hiccups.. At least nine people were arrested for drugs. And there were at least 80 ambulance responses per day.
"It was a long event. And there were a lot of people there... got overwhelmed... people who drank too much," McCarthy said.
Lollapalooza means big bucks for the city. Last year's concert brought in more than $120 million, festival organizers say. Mayor Rahm Emanuel said he is proud that it will be a big tourist attraction for many years to come.
