Jay-Z's Yankee Stadium show ran nearly three hours late. Fans stormed the gates, the start time slid to 12:18 a.m., and the last note didn't hit until around 3 a.m. Billboard asked the obvious question nobody had answered yet: did anyone actually get fined for that?

Billboard writer Delisa S., who was there, had the same questions I'd have: How do the city's noise and curfew laws apply to a stadium show? Who actually decides whether it goes on? What would pushing a concert that late cost Jay-Z or Live Nation? And has this happened before?

Turns out the Billboard staff didn't really know — but Delisa did have a great time, she explained in a snappy, cute video posted to Billboard's website. Good for her.

She certainly piqued my interest, so I'm going to try my best to figure it out.

The first question I'd ask is: who would know the answer here? Live Nation, for one, and the team at Jay-Z's company Roc Nation. That's probably the easiest way to get an answer — I reached out to my main contact at Live Nation who told me she hadn’t heard anything about fines being issued.

Then there's the permit maze. Staging a major concert or festival in New York normally means running the gauntlet of the Health Department, City Parks and the State Liquor Authority, among others. But since this show was at Yankee Stadium, most of that gets absorbed into the Yankees' existing permit to operate the ballpark.

Still, Live Nation likely needed a permit from the NYPD for a major concert at Yankee Stadium, since concerts aren't the venue's primary use, as well as a permit from the Department of Environmental Protection, which enforces the city's noise rules. Both the NYPD permit and the DEP permit would specify noise levels and curfew times for the venue, as well as spell out penalties for exceeding them.

Getting a copy of the actual permits requires a Freedom of Information Law request — you can read the ones I submitted here and here. Don't hold your breath: agencies get up to 20 days just to decide whether the request is legitimate, and the actual documents can take weeks or months after that. New York moves fast for a lot of things. FOIL isn't one of them.
