A little while back, Pearl Jam’s Eddie Vedder scored a documentary about Robert F. Kennedy called Return To Mount Kennedy. His soundtrack for the movie has yet to be released, but one of the instrumentals he composed for the film has just been put out as the latest entry in Sub Pop’s singles club. The track, “Cartography,” also comes with a B-side remix by Yeah Yeah Yeahs’ Nick Zinner. All proceeds from the release will support Fair Fight, an organization dedicated to preserving a secure election.

“Listening to the speech delivered by Bobby Kennedy in regards to the assassination of Martin Luther King Jr. 50 years ago, you are reminded that once again we are at a moment in time when our society can and must do better,” Vedder said in a statement about the release. “Voting is our most powerful form of nonviolent protest. And those whom we vote for must be made deeply aware that the issues of equality and justice in America are of the utmost importance and need to be not only restored but taken to the next level. NOW.”

Check out “Cartography” and its Zinner remix below.

“Cartography” is out now via the Sub Pop Singles Club.
