Live Earth, the biggest international rock event so far — with shows on every continent, including a small one in Antarctica — was presented as an attempt to save the human race from global warming. The concerts were accessible online, on satellite radio and on television, overlapping for more than a full day of music from the Police, Kanye West and Dave Matthews (New Jersey), Madonna (London), Shakira (Hamburg, Germany), Linkin Park (Tokyo), Sarah Brightman (Shanghai) and Vusi Mahlasela (Maropeng, near Johannesburg), among many other stars.
