Artists like Dave Matthews Band and Jack Johnson have done great things on their tours to bring their music to the masses in an earth-friendly way.

But now -- in honor of the 40th anniversary of Earth Day in April -- we're turning to you, the music fan, to share ideas on how everyday people can make rocking out greener.

Have a good green music tip? Know how to green getting to the show, recycling media, reusing merch or something completely new?

Share it with us and your name and idea could wind up posted here on and printed in Billboard magazine!
