Sunidhi Chauhan

Sunidhi Chauhan, a leading singer in Indian cinema, was announced Wednesday as a new performer for next week’s major anti-poverty concert in New York.

The Global Citizen Festival, which hopes to spur activism to fight extreme poverty, has already announced Western superstars Beyonce, Pearl Jam, Coldplay and Ed Sheeran as headlining acts.

Revealing further acts for the Sept. 26 show in Central Park, the festival announced an appearance by 32-year-old Chauhan, considered one of her generation’s leading playback singers, who record songs for Indian films as actors lip-sync.

Other newly announced performers include Common, the popular rapper and actor who co-wrote the Oscar-winning song “Glory” from the civil rights drama “Selma.” The singer Usher, the Indian actress Freida Pinto and US film and television stars Katie Holmes and Laverne Cox were separately announced as part of a host committee that will mobilize fans in Central Park as well as social media users. Stephen Colbert, who recently started as host of CBS television’s premier “Late Night” show, was previously announced as the event’s host.

Launched in 2012, the Global Citizen Festival coincides with the annual UN summit and gives out tickets to fans who commit to take actions against poverty.

The festival is broadcasting internationally for the first time this year, hoping to build pressure as the United Nations announces new targets at the end of its 15-year push known as the Millennium Development Goals.
