Russian authorities are on the cusp of possibly sentencing three female punk rockers to three years in a labor camp as punishment for their performance earlier this year in an Orthodox church in which they performed protest songs and voiced their opposition to President Vladimir Putin. The prosecution and trial of Pussy Riot has angered music fans and activists around the world, as the rockers were literally put on display in a glass cage in a Moscow courtroom this week.

But Pussy Riot is getting some emotional support from D.C.’s music community tomorrow night, when four local bands play a protest show on the doorstep of the Russian Embassy at 2650 Wisconsin Avenue NW.

The show, organized by Amnesty International, features the Baltimore-based hardcore quintet War on Women, the punk act Mobius Strip and D.C. indie-rockers Brenda and Sad Bones.

Pussy Riot’s trial, which is expected to end with a verdict on August 15, has been described as a legal circus. Writing for The New Yorker, Masha Lipman callied it a “outrageous, astonishing, biased, exhausting, ridiculous, and at times comic spectacle.” Journalists attempting to cover have been given the bum rush out of the courthouse, complete with jeering and pushing as they’ve been ejected.

Amnesty International’s Pussy Riot rally starts tomorrow at 5:15 p.m. Though the forecast calls for rain, an organizer wrote on the event’s Facebook page that the show will happen regardless of the weather.
