For this mother of all pyrotechnic displays, Macy's will explode more than 40,000 fireworks choreographed to a 25-minute patriotic playlist, courtesy of R&B superstar Usher. During the big finale, turn eastwards for mirroring lights on the top of the Empire State Building, where a mashup of Frank Sinatra's "New York, New York" and Jay-Z's "Empire State of Mind" will set the show. Stake out a nice spot along the Hudson to watch, and bring your own picnic basket with beverages to toast our country's birthday. All ages.
