The members, Nadezhda Tolokonnikova and Maria Aloykhina, were released in December, under an amnesty bill passed by Russian President Vladimir Putin. As Rolling Stone reports, the artists will appear at Amnesty Internationals Bringing Human Rights Home concert on February 5th, at the Barclays Center in Brooklyn. The political activists were sentenced to two years in prison in 2012 for staging an anti-Putin performance inside a Moscow cathedral. They ended up serving 21 months before being released, though Tolokonnikova and Aloykhina remain fiercely anti-Putin and have dedicated themselves to supporting the rights of political prisoners around the globe.
