The case against the three women of Pussy Riot—-the Russian feminist punk collective whose Nadezhda Tolokonnikova, Maria Alyokhina, and Yekaterina Samutsevich could be sentenced to three years in a labor camp for performing a protest song in a Russian Orthodox church—-has captivated activists and musicians worldwide. Tomorrow evening, D.C. will get a chance to show support when Amnesty International hosts a free concert outside the Russian Embassy, in what promises to be the most punk rock thing to happen in Glover Park since Henry Rollins moved out.

The bill features the aptly named, Baltimore-based hardcore five-piece War on Women, who recently released the brutal LP Improvised Weapons on Exotic Fever Records. Repping D.C. will be jangly indie-poppers Brenda, political punk mainstays Mobius Strip, and scrappy indie-rockers Sad Bones.

Amnesty International has declared the three women “prisoners of conscience” and are urging people to sign this petition demanding their release. “We need everybody to get involved and take action,” says Amnesty International Media Relations Director Sharon Singh, who has helped organize the event. “Amnesty is showing the Russian authorities that people around the world, especially in the United States, are very concerned about the state of these women and the fact that they’re being held solely for their political beliefs.”

The show starts at 5:15 p.m. The forecast calls for rain, but an Amnesty representative states on the event’s Facebook page that tents and ponchos will be provided and that the show will go on no matter what.

The original version of this blog post inaccurately said Pussy Riot’s controversial performance took place in a Catholic church. It was a Russian Orthodox church.
