Following a performance by Widespread Panic at East River State Park in Williamsburg on Saturday night, crowds milled about the neighborhood, huffing on nitrous oxide filled balloons as helpless residents watched on in horror.

One woman described them as a “drug orgy mob nightmare” and shot footage of their lawlessness, which she promptly uploaded to YouTube with a description that sounds more like something you’d expect at the Gathering of the Juggalos than on North 7th Street:

Nitrous oxide dealers with huge tanks set up shop to booming business with no police in sight. The hissing sound you hear is coming from the nitrous oxide tanks.

Of course there were no cops. It was a rock concert, not a rap show.
