The show went on at two New Jersey concerts over the weekend despite violence and a panic attack.

New Jersey State Police report at least three arrests at the Summer Jam concert inside MetLife Stadium in East Rutherford on Sunday night because of a floor fight that sent folding chairs flying. Spokesman Lt. Brian Polite said there were a total of 35 arrests at the concert most of which were on charges typical of big events at the game such as the selling of merchandise without a license and disorderly conduct.

According to the Bergen Record, State Police said one person was stabbed in the back of the head at the show featuring Fat Joe and Remy Ma. In 2015, 61 people were arrested and 10 state troopers were injured during a clash outside Summer Jam.

The threat of thunderstorms led to the cancellation of the preconcert Festival Village and a delayed start to the concert.

A concert with the Dolan Twins at the iPlay America entertainment complex in Freehold got off to a rough start on Saturday night after seven people were hospitalized for a "heat related issue," according to the Monmouth County Sheriff's Office. Neptune Township EMS reported over 20 people were treated at the concert.

On its Facebook page, iPlay America wrote that attendees crowded the stage as the concert featuring the 16-year-old YouTube stars got underway and "caused some of those who were closest to the stage to panic." The Asbury Park Press reported it was very warm inside the concert hall and several girls got pinned onto the floor as the crowd pushed forward.

Police and staff told the attendees to sit down. Grayson Dolan tried to help calm down the crowd with a tweet urging everyone to "take a seat and a deep breath."
