Stevie Wonder will headline Global Citizen Live in Los Angeles. The concert takes place at outdoor venue The Greek Theatre on September 25 and will air live on BBC One the same day, and on ABC on September 26th. Tickets to attend the Los Angeles festival are available now.

“It is again my pleasure and honor to join with all of the artists who are using their gift of song to celebrate the Global Citizens’ event by doing our part in working against global warming, starvation, and singing for equality around the world,” Stevie Wonder said in a statement. “We Are The Village!!!”

Adam Lambert, Demi Lovato, H.E.R., Chloe x Halle, OneRepublic, Ozuna, the Lumineers, and 5 Seconds of Summer will round out the Los Angeles lineup.

The international advocacy organization also announced the lineup for its London edition, which features performances by Duran Duran, Kylie Minogue, Nile Rodgers and Chic, among others. The London location has not yet been disclosed.

“Over the past year and a half we’ve all faced fears about our health, food availability, and climate change. I see Global Citizen Live as a megaphone that can point the power of the people directly at those with the ability to make the worldwide, systemic changes needed to protect the most vulnerable people and to defend our planet,” Rodgers said in a statement. “Now is not the time for wealthy countries to cling to nationalist ideals and refuse to prioritize foreign aid and support to those in dire need. On September 25 we will gather the world to watch as leaders commit their intentions to act as responsible global citizens. And it’s our job to cry out when promises aren’t fulfilled. We want to encourage our leaders to ensure there are good times ahead for everyone.”

Performances by BTS, Usher, Andrea Bocelli, Green Day, Keith Urban, Lorde, Metallica, and Ricky Martin will round out the 24-hour, “day of unity” broadcast event, which will also feature cuts to concerts taking place in ticketed, Covid-19 compliant spaces in various locations.
