"Change only takes place when and where there is action," rapper Jay Z said in a statement, via Rolling Stone. "I'm joining the 2014 Global Citizen Festival because I believe through actions, whether it be by raising awareness, getting involved or educating ourselves, the goal to end extreme poverty by 2030 is possible."

"Global Citizen will be the first show No Doubt has played together in two years," No Doubt's bassist and co-founder Tony Kanal explained. The open-air concert will mark the end of No Doubt's extended hiatus after lead singer Gwen Stefani chose to pursue her solo career.

"It's a great way to get us back on stage. It was such an honor to be asked to play this particular concert. It's unacceptable that over 1 billion people live in extreme poverty, and it's got a pretty eclectic line-up, which reflects the event's true spirit of diversity," Kanal added.

"I am incredibly honored to be part of this year's lineup for the the Global Citizen Festival in Central Park and to add my voice and the voices of my fans to those calling on the world's leaders to throw their weight behind GPP's efforts.
