US pop star Madonna is to head the British contribution to a global series of Live Earth concerts to be played across seven continents on July 7 this year, it was announced Tuesday.
The pop diva will be joined by Genesis, James Blunt and the Red Hot Chili Peppers to front the show at London's Wembley stadium. Other groups include Foo Fighters, Duran Duran, Snow Patrol and Razorlight.
The diverse line-up is also likely to include rap group The Beastie Boys, singer-songwriters David Gray and Damien Rice, and R&B pianist John Legend.
Organisers said that tickets would be allocated though a ballot, and fans would be able to register their interest online for 72 hours from 6 am (IST) Friday.
Tickets, priced at £55 ($108) each, would be limited to two per applicant and could be purchased from Wednesday, April 18.
Concerts are also scheduled to take place in Johannesburg, Rio de Janeiro, Shanghai, Sydney and Tokyo.
The concerts aim to set a "green example" for other music events by using measures such as eco-friendly electricity, sustainable lighting and carbon-neutral travel.
Former US Vice President Al Gore, who is one of those involved in organizing the series of events, said he expected Live Earth to attract "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," he said.
All profits will go to organizations including the Alliance for Climate Protection, the Climate Group and Stop Climate Chaos.
