Superchunk have a new, limited-edition charity 7" single that benefits Bill McKibben’s climate-change advocacy non-profit Both sides of the single are pretty special: the a-side, "Our Work is Done," features Fucked Up's Damian Abraham, while the b-side is a cover of Klaus Nomi's classic 1981 single "Total Eclipse." Here's more from Superchunk's Mac McCaughan:

“Our Work Is Done” is an imaginary conversation between the last two living residents of a hot and dying planet. Damian Abraham from the band Fucked Up lends his gravitas to the situation. “Total Eclipse” is a song about a different kind of holocaust, originally performed by Klaus Nomi. When I saw the film Urgh! A Music War, the Nomi clip blew my mind. I didn’t know what to make of him or the performance. Truly a unique artist trying to convey the urgency of several emergencies at once.

The news these days is overwhelming, and sometimes it’s hard to focus on the larger issues we are all collectively facing. Climate change is transforming the world in dangerous ways and requires immediate action. The proceeds from the single will go to Bill McKibben’s, and we stand by them as they build the global grassroots climate movement that can hold our leaders accountable to the realities of science and the principles of justice.

The 7" is available now in two variants: 250 numbered copies on black vinyl, and 290 numbered copies on mint green marble vinyl, with sleeves signed by all four members of Superchunk. You can listen to both sides, and watch that classic Urgh! footage of Klaus Nomi, below.

Fucked Up were just in Brooklyn for two shows in support of their new album; Superchunk toured earlier this year for their new album, What a Time to Be Alive.
