Several high-profile music acts have joined a new initiative that rewards fans for social activism. Beyonce, Pearl Jam, Bruce Springsteen, One Direction, Jay-Z, Kanye West, Usher, Ke$ha, Foo Fighters and Neil Young are among those who signed up for the Global Citizen Tickets Initiative.

The campaign allows fans to accumulate points when they help further change by signing petitions, contacting government representatives, or raising money for charity. Points can be used towards a lottery to win free concert tickets.

Over the next three years, each of the acts involved will give away one pair of tickets to every one of their shows.

The man behind the initiative is Pearl Jam manager Kelly Curtis, who came up with the idea while putting together the 2012 Global Citizen Festival in New York City. The event featured Neil Young, Foo Fighters and the Black Keys, and raised $1.3 billion for anti-poverty organizations.

He told Rolling Stone magazine: "I'm hit up every day for something, whether it's to play or donate a song or give money. I just thought, 'What would accomplish a lot that wouldn't require time or anything - what if everyone gave a show?' You're talking about social activism in a really great way."

British boy band One Direction told Billboard magazine: "We are thrilled to be part of the Global Citizen campaign - a brilliant way to reward fantastic volunteers fighting against global poverty. We can't wait to see some 'global citizens' at our shows!"
