It’s almost time for one of the biggest moments in music, and we’re not talking about the Grammys.

Global Citizen, an organization aimed at fixing the world’s largest problems with the help of everyday people known as Global Citizens, has its annual all-day music festival on Saturday in New York City.

Last year, the festival had huge headliners, such as Kendrick Lamar, Rihanna, Chris Martin, Eddie Vedder, Ellie Goulding, Demi Lovato and more. This year, while the performers are different, the star power is just as strong.

Here’s who will be performing at the event, though the line-up is subject to change should something come up and an artist is unable to perform:

Stevie Wonder, Green Day, The Killers, The Lumineers and The Chainsmokers are headlining the event, while Pharrell Williams, Big Sean, Andra Day and Alessia Cara will each have special performances.

In order to gain access to the this huge concert and be able to see it in person, rain or shine, at the Great Lawn at Central Park in New York City, fans had to earn the tickets by completing actions on the Global Citizen Festival website. Once enough actions were completed and the tickets were earned and won, there was no fee attached to the general admission tickets. VIP tickets, which guarantee access to specific location at the concert, are also available on Ticketmaster for a fare.

For those who weren’t able to earn tickets or who live too far away to attend, don’t worry. You’ll still be able to watch the concert. Global Citizen Festival will be streamed live on YouTube starting at 4 p.m. EDT on Saturday. Viewers can go to the Global Citizen YouTube page to watch it. It can also be viewed on Twitter, MSNBC and MSNBC.com, as MSNBC had partnered with the organization for the fourth consecutive year.

This event marks the end of Global Citizen Week, which was from Sept. 17 until this Saturday. The weeklong programming event featured panels, activations, speakers and performances that were all meant to motivate and inspire people to do their part to help make the world a better place.

Some of the events they had during the week included a performance with Mumford & Sons on Monday to support the Global Citizen and Children in Conflict initiative. There were also performances by Andra Day and Demi Lovato at the Cadillac House as part of the “Accelerator Series,” on Tuesday and Thursday, respectively. There were store activations at Lululemon, conferences at Columbia University and a summit aimed at inspiring younger generations to travel.

Now that the finale event is just about here and while those watching from the comforts of their homes don’t have do anything until 4 p.m. EDT, those going in person should arrive earlier. In order to have the closet viewing spot for the duration of the event, ticketholders should arrive right when doors open at 2 p.m. EDT, but, of course, waiting in line outside of the doors even earlier will help ensure an even better spot on the lawn.
