It's that time of the year once again. Sure, the country will be celebrating the 4th of July this Thursday, but it's an even bigger deal in Philadelphia. Of course there's the city's historical significance, but there's also Philly's Fourth of July Jam. As America's largest free concert, it draws over 600,000 people annually and in honor of its 20th anniversary, the show will be broadcast to 95 million homes from 8 p.m. until 11 p.m. Thursday night. 

Comedian and Philly native Kevin Hart will host the concert, which will feature performances by The Roots (who will also serve as the house band), Demi Lovato, Ne-Yo, John Mayer, J. Cole, Jill Scott, Marsha Ambrosius, Grace Potter and more. 

If we haven't already stressed it enough, the concert is free. Make sure you're on the Benjamin Franklin Parkway to enjoy the party this Thursday. Get more information about the entire weekend's festivities here.
