Following their two-year prison sentence last week, artists have stepped up to take further action in support of jailed Russian punk band Pussy Riot.

Björk, who recently dedicated "Declare Independence" to the band, is now selling Pussy Riot T-shirts in her webstore to help the group pay legal costs, and prevent their children from being put into foster care. That's one design, above; another is below. Men's and women's sizes are available for £20 each with all profit to Pussy Riot.

On August 27, Vivian Girls will play a Pussy Riot benefit show at the Smell in L.A. The lineup also includes Pangea, Haim, and Kremlin Head (which features members of No Age and Mika Miko performing punk covers). Proceeds will benefit the Pussy Riot Legal Defense Fund; tickets are on sale now.

Also this week, the Austin Punk band Trail of Dead released a new track, "Up to Infinity", which they dedicated to Pussy Riot.

Reuters confirmed Monday that Russian police are currently searching for more members of Pussy Riot. (The band comprises approximately 10 members; three are jailed.)
