You may have been wondering just how Al Gore’s been filling his time since decorating his mantle with a much-deserved Oscar for An Inconvenient Truth. Or maybe you’ve already caught wind of the epic day of live day of concerts he’s been planning. It’s called Live Earth, and on this coming Saturday (7/7/07), star-studded lineups will be belting out a global S.O.S.—in this case to “Save Our Selves.”

Rocking New York City, London, Johannesburg, Rio de Janiero, Toyko, Shanghai, Hamburg, Sydney, and even a special show from a research station in Antarctica, all seven continents will be well represented by some of pop music’s biggest names like Kanye West, Alicia Keys, Kelly Clarkson, the Smashing Pumpkins, the Police, and Madonna, who actually penned a tune for the cause.

Besides Big Al, there are a bunch of partners who’ve come together to make Live Earth such an ambitious event. Kevin Wall, who helped produce the Live Aid shows, supposedly presented the idea to Gore awhile back. They then rounded up some sponsors and partners, including MSN, the exclusive web-media partner who’ll be offering live simulcasting all day Saturday and who’s hosting the impressive and wildly comprehensive Live Earth website. Seriously—you could spend a day poking around the site, surfing from carbon pledges to green living tips to event details to multimedia videos and songs. Take some time and check it out.
