The residents of Dyckman Street – in Upper Manhattan – celebrate the Fourth of July each year with a fireworks display that is as spectacular as it is illegal.

Last year, a group of cinematographers documented the event.

At first, “The Incredibly Spectacular Dyckman Fireworks Co.,” which was released online on Monday, seems a cheerful record of what happens beneath the fireworks:

Grills sizzle, teenagers preen, old women titter.

But then it gets crazy.

The streets cloud with smoke, sparks fly, the police arrive.
