Green musicians

Going green rocks!

These days, when it comes to championing green causes, artists and musicians (like Guster, pictured) are doing more than ever to practice what they preach. Never mind just filling up the tour bus with biodiesel—here are 10 acts that are doing everything from starting their own eco-friendly non-profits to designing their own hybrid cars to joining scientific research expeditions to Greenland. Here’s hoping their examples will inspire you to get more involved in environmental issues this Earth Day—or all year long.—Andy Hermann, Metromix
