Pussy Riot are a Russian, feminist punk rock band, who became the focus of an international campaign after their arrest for staging an anti-government protest.

They've received a two year prison sentence for a staging a guerrilla concert in a church, in protest of the Russian President Vladimir Putin.

My Russian might not be good enough to understand their music, but locking up these women is certainly over the top for what is essentially a political performance.

We might never be able to fully comprehend the quick riffs and screaming vocals of Pussy Riot, but their imprisonment sounds exactly the same as free speech dying.

And isn't free speech one of the most basic foundations of a free society?

For a country that carries itself as a world leader, Russia has significantly risked its reputation to stop a punk band from criticising its leader.

It is important to acknowledge that their protest did offend many Russians, but imprisoning people because they are offensive still violates the right to free speech and speaks little for the jailor’s character.

Here at Amnesty, we challenge the Russian authorities to take the criticism.

And when all else seems like it's failing, our experience campaigning on thousands of political prisoners has taught us that the key to securing Pussy Riot's freedom, and defending the principles of free speech, will be visibility - otherwise it is all too easy for the world to forget three women in a remote Russian prison colony.

So we need your help with three things to keep Pussy Riot visible:

1. Get a balaclava, take a selfie and post it here

2. Send an email to Russian Prosecutors via my colleagues at Amnesty USA

3. Share this blog on Facebook, Twitter, Digg, Pinterest, or talk about it at dinner with friends... do whatever you can to help Pussy Riot's case stay visible.
