Macy's 4th of July Fireworks: what you need to know

This year's Macy's 4th of July Fireworks show will be the 40th year of the tradition enjoyed by millions of people across the country.

The show will set off at 9:20 p.m. from five barges along the East River allowing for spectacular viewing from Manhattan, Brooklyn and Queens and to a lesser degree from towns along the Hudson River in New Jersey.

Macy's is also offering an app to follow along, the Make Light application changes the color on your device to match those of the fireworks.

A 25-minute long song track will accompany the show.

Some of the new features during this year's spectacular will include 22 colors of fireworks, ghost fireworks which appear, disappear and appear again, emojis that wink and writing in the sky.

Legendary singer Jennifer Holliday will perform her rendition of 'America the Beautiful.'
