Inspired by US Vice President Al Gore and his Oscar-winning documentary, "An Inconvenient Truth", Wall co-created Live Earth, a global concert event designed to raise environmental awareness and combat climate change. On July 7, 2007, 150 musical acts, including The Police, Alicia Keys, Metallica, and Kanye West performed at eleven locations around the world in concerts that were broadcast globally through television, satellite and terrestrial radio, handheld devices, and the internet. The event set a live-streaming record as 237,000 people watched video coverage from MSN simultaneously. Live Earth reached an audience of nearly two billion people and set live streaming records, with 15 million streams initiated during the live event, and 100 million the following week.
