Krewella, Alvin Risk and more will play the one-day event, which will emphasize international child survival.

Tiësto will headline the first-ever Thank You Festival, a multi-act music showcase presented by the Global Citizen movement in partnership with World Childhood Foundation. The fest, which will recognize U.S. efforts to eliminate globla child deaths over the past 25 years as well as stress the needed support for the world's children, will take place on June 26 at Merriweather Post Pavilion near Washington, D.C.

Along with Tiësto, Above & Beyond, Krewella and Alvin Risk have been confirmed as the Thank You Festival's initial performers, with more to be announced later. Tickets go on sale this Friday (Apr. 11), and 100 free tickets for the event, produced by AEG Live, will be given away at Global Citizen's web site.

Tiësto, Icona Pop Duet at Ultra Fest: Full Recap

"To become a global citizen, we must extend our compassion beyond our borders. The United States has played a pivotal role in leading child survival and protection efforts worldwide and this event celebrates that," says Hugh Evans, CEO of the Global Poverty Project in a press release. "But this is also a chance to educate the younger generation and motivate our leaders to act. The bottom line is increased investment in child survival initiatives could ensure that no child dies for the lack of a 30-cent vaccine."

The Global Poverty Project, which was founded in 2008, launched the Global Citizen Festival in 2012, and artists like Stevie Wonder, Foo Fighters, Alicia Keys and Neil Young & Crazy Horse have since played the annual event in New York's Central Park. Earlier this year, the organization kicked off the Global Citizen Nights concert series with the Fray and Allen Stone performing at the first free, ticketed show on Mar. 10 in Austin, Tex.

Tiësto added in a statement, "Through my work with the World Childhood Foundation, I've learned about the millions of kids who are battling abuse and even dying from diseases that have known cures. I hope all my fans will join me in working with these amazing organizations to help these children all around the world live and become healthy and strong so they can enjoy their childhoods."
