The Green Music Group is at it again! A few weeks ago, Stefan Lessard from the Dave Matthews Band kicked off the organization’s Green Music Challenge by asking us to volunteer in our communities.

Challenge two comes from Sheryl Crow, who urges us to write a letter to our Representative or Senator in Congress in support of strong, effective environmental legislation. It’s all part of the Green Music Group’s plan to help the music industry  - and music fans – to be better environmental citizens.

Writing a letter sounds like a lot of work, but maybe the fact that it requires effort is the reason why it’s such a successful advocacy tool. Taking the time to share your opinion on environmental policy sends a powerful message to Congress that this issue matters to their constituency.

To enter the challenge’s drawing for a Patagonia prize pack plus a shot at winning a 2010 Honda Insight Hybrid, take a photo with your local representative or Congressional office staffer or even a shot outside your district office. Upload the shot to the Green Music Group’s website by noon EDT on Friday, May 7, tag it with the word “TWO,” and you’re entered to win!

Headcount is sweetening the deal by giving away a free “Best of Bonnaroo” compilation download featuring exclusive tracks from the Dave Matthews Band, Jack Johnson, Ani Difranco, Wilco, Guster, and more to everyone that uses the Headcount tool to write their Senator, local newspaper, or the President.
