Matthew Modine, DJ Spooky and Boris Kodjoe on Earth Day

Artist and turntablist Paul D. Miller (aka DJ Spooky) is working on Sinfonia Antarctica, a musical/film performance based on field recordings he made of Antarctica's rapidly changing environment. "McMurdo [station] is like McDonalds -- I wanted to get deep into the ice fields," he says. After performing some excerpts at the Green Apple Festival in Washington, DC he spoke with TreeHugger about building a bigger tent for the environmental movement, the relationship of remixing to environmental awareness, and his obsession with ice.
