On July 7, 2007, more than 100 musical acts performed at a series of world-wide concerts collectively called "Live Earth", kicking off a multi-year campaign to combat climate change and advocate environmentally sustainable living. The CD/2DVD "Live Earth" package brings together the most popular artists and best performances at Wembley Stadium in London, Giants Stadium in New Jersey, and Makuhari Messe in Japan from this truly global music summit.
