Well, alarmism isn’t working anymore, so let’s try bribery:

The Bonnaroo Music & Arts Festive, Headcount, and the NRDC Action Fund have organized a collaboration of top music artists to encourage Americans to contact their elected officials about climate change. To aid in this, Pearl Jam, Dave Matthews Band, Phish, Jack Johnson, Wilco, The Decemberists, and many more artists provide music tracks for free downloads.
Best of Bonnaroo is a 17-track collaboration from the live festival. You are asked to email your Senator, the President, or your local newspaper in exchange for receiving these free downloads however, it’s not required that you do so.
