Some of the biggest acts in music are confirmed for the New York area and London installments of the Live Earth concerts, happening worldwide on July 7. The Police, Smashing Pumpkins, Roger Waters, Dave Matthews Band and Kanye West will play at Giants Stadium in East Rutherford, N.J., while Madonna, Red Hot Chili Peppers, Genesis, Beastie Boys and Foo Fighters will perform at London's Wembley Stadium.

The other locations for the global warming-focused concerts are China (Steps of the Oriental Pearl Tower, Shanghai), South Africa (Johannesburg Cradle of Human Kind), Australia (Sydney Aussie Stadium), Brazil (Rio de Janeiro's Copacabana Beach) and Japan (Tokyo Dome). Lineups for those shows have yet to be announced.

At Giants Stadium, the bill will be rounded out by AFI, Akon, Alicia Keys, Bon Jovi, Fall Out Boy, John Mayer, Kelly Clarkson, KT Tunstall, Ludacris, Melissa Etheridge and Rihanna.

The London show will also feature the Black Eyed Peas, Bloc Party, Corinne Bailey Rae, Damien Rice, David Gray, Duran Duran, James Blunt, John Legend, Keane, Paolo Nutini, Razorlight and Snow Patrol.

The concerts will be streamed live at LiveEarth.MSN.com. U.K. ticket sales will be allocated by ballot, and a 72-hour registration period begins Friday (April 13) at LiveNation.co.uk/liveearth.

Live Earth will also be broadcast on BBC television and radio in the U.K. and via more than 120 networks around the world to a potential global audience of approximately two billion.

Concert organizers plan to use eco-friendly electricity and carbon-neutral travel to set an example. "By attracting an audience of billions, we hope Live Earth will launch a global campaign giving a critical mass of people around the world the tools they need to help solve the climate crisis," said former United States vice president Al Gore, who helped organize the events. "But ultimately, corporations and governments must become global leaders taking decisive action to stop global warming."
