Organizers of the planet-spanning Live Earth concerts revealed on Tuesday the all-star lineups for the U.S. and U.K. legs of the event, set to take place July 7 at Giants Stadium in New Jersey and Wembley Stadium in London respectively.

The artists headlining the concert in the States include Alicia Keys, Kelly Clarkson, Dave Matthews Band, the Police and the Smashing Pumpkins, while the Beasties Boys, Madonna, Red Hot Chili Peppers, Black Eyed Peas and Duran Duran are among the acts slated to take the stage across the pond.

The 24-hour musical event will span all seven continents, with concerts at Johannesburg's Cradle of Human Kind, Sydney's Aussie Stadium, Rio de Janeiro's Copacabana Beach, Tokyo's Tokyo Stadium, Shanghai's Oriental Pearl Tower and an as-yet undetermined location in Antarctica.

Modeled after Bob Geldof's Live 8 and Live Aid concerts, which were designed to raise awareness of African poverty, Live Earth is intended to educate the planet on how to combat global warming.

"This monster lineup will ensure Live Earth meets our goal of bringing together people from around the world to combat the climate crisis," Live Earth founder and executive producer Kevin Wall said in a statement Tuesday.

The concerts will serve as the launching pad for a new initiative called Save Our Selves—the Campaign for a Climate in Crisis. Proceeds from the event will benefit the Gore-chaired Alliance for Climate Protection.

Organizers are hoping to reach an audience of 2 billion people over the course of the 24-hour event. More than 120 networks around the world will broadcast the concerts, with NBC and VH1 airing them in the U.S. The event will also be streamed live online by MSN.com.

Live Earth will kick off in Sydney on July 7 and progress across the globe, concluding with the performances at Giants Stadium.

"We hope the energy created by Live Earth will jump start a massive public education effort," Gore said in a statement. "Live Earth will help us reach a tipping point that's needed to move corporations and governments to take decisive action to solve the climate crisis."

Tickets for the shows go on sale Monday.
