Bon Iver, Gracie Abrams, and the National’s Aaron Dessner have released a new song, “Sold Out,” to benefit the gun violence prevention organization Everytown. Though Justin Vernon has often collaborated with Dessner, and Abrams and Dessner are ongoing songwriting partners—not to mention that Abrams has covered Bon Iver’s “Beach Baby”—“Sold Out” is the first formal collaboration between Vernon and Abrams. Head to Bandcamp to buy the song, which has not been made available to stream.

The three artists said in a joint statement that they made “Sold Out” last year in the wake of a school shooting. “We were reminded of it this week as our hearts were broken yet again,” they wrote, apparently referring to the Brown University shooting. “It’s a sad one to share during the holidays, but the world is hurting and we shouldn’t look away. We are proud to support Everytown, an organization dedicated to ending gun violence in America. We are releasing this song to raise awareness of their mission of reducing gun violence. Please visit their website for more information on the unbelievable work they do. Sending so much love to you all.”
