Here's How You Can Watch Rihanna, Metallica and More at the Global Citizens Festival

Musicians and entertainers including Rihanna, Kendrick Lamar, Demi Lovato, Neil Patrick Harris and Connie Britton will gather in New York City's Central Park on Saturday for the fifth annual Global Citizens Festival, a free music festival designed to increase awareness about issues facing people in various parts of the world.

Though admission is free (aside from paid VIP tickets available for purchase on Ticketmaster), fans have to perform a series of "actions" aimed at ending extreme poverty -- i.e. reaching out to government leaders on social media -- in order to accumulate points to make them eligible to win tickets. But if you weren't among the 50,000 or so people who managed to score a ticket, you can still watch from the comfort of your living room. (The final ticket lottery took place on Sept. 19, so if you don't have a ticket by now, you're out of luck.)
