On July 7, more than 100 bands, including Sting and his old Police mates, will rock all seven continents for Al Gore's Live Earth concerts. And while the idea of partying to save the world has been around since Bob Geldof's Live Aid, in 1985, this spectacle has a twist: The indie-folk fusion band Nunatak, five twenty-something British scientists sequestered at the British Antarctic Survey's Rothera Research Station, on the Antarctic Peninsula, will play the bottom of the world in the dead and dark of winter. "The rest of the acts get their girls and drugs handed to them on a plate," says guitarist Matt Balmer. "We have to work for our good times." Good luck finding groupies in a sold-out crowd of 17. Live Earth will be Web-cast at msn.com.
