Bostonian musicians Mike Gintz and Jordyn Bonds have launched a September-long campaign to crowd-fund a full-page ad to run in the Wall Street Journal, calling out influential world leaders “for failing their children by failing to address climate change.”

The Indiegogo campaign, dubbed The Open Letter, has until the end of the month to raise $161,000 — the cost of running a full-page ad in one of the world’s most respected newspapers, plus the additional expenses using Indiegogo and the associated credit card and PayPal fees. That shit certainly ain’t cheap.

The project, launched Sunday, is already off to a good start, and the letter has been approved by the Journal’s review board.

“The campaign’s currently live and we’ve made 10% of our goal during our first 24 hours – pretty great for a holiday weekend,” reports Gintz this morning. “Success from here on out depends on maintaining that momentum.”

Both Gintz and Bonds are known figures in the Boston music scene. Gintz plays in one-half of weirdo-pop duo Hex Map, plays in Kevin Micka’s Animal Hospital Ensemble, and previously held court with beloved Boston bands like Clawjob and Clickers (whose 2005 split with Night Rally will pretty much live forever). Bonds, meanwhile, has a musical resume just as impressive, currently as solo project Permafav, and before that leading charges in Polaris Mine and Big Bear.

But for now, their music is taking a back seat to the climate-change cause.

“Help us put leaders of governments, CEOs, media moguls, and the ultra-wealthy on the hook morally to address climate change,” the campaign’s description declares.
