Jay Z, Beyonce, No Doubt And More Performed At The Global Citizen Festival -- Here's Why

FInd out about the cause.

CENTRAL PARK, New York -- Jay Z. Beyonce. No Doubt. Sting. Carrie Underwood. fun. The Roots. Alicia Keys. Tiesto.

All of these artists could probably command triple digits for a ticket to see them play live alone. And together? Better start saving.

But on Saturday, they all performed together -- and it was free to get in.

Why?

The Global Citizen Festival.

The third annual event was put on with the goal of erasing extreme poverty by 2030. That sounds like a tall task, sure, but that's why the organization has enlisted so many big names -- both to help raise awareness about the issue, and to put pressure on world leaders to do their part in eradicating that poverty.

All of the acts performed for free, and of the 60,000 attendees, the vast majority got their tickets for free, though some bought VIP entrance. Those who didn't could earn their way in by committing to "take action" which allowed them to "earn points" they could put towards entry.

The many performances throughout the day-long festival were bridged together by short spiels and speeches by celebrities and world leaders. Celebs like Hugh Jackman, Jessica Alba and Olivia Wilde plus political leaders like United Nations Secretary-General Ban Ki-moon and President Barack Obama (who actually recorded a video message) were on hand to highlight some of the facts and help announce steps towards solutions.

Here's why so many of your favorites are already involved, and what's being done:
