Opposition to the unfair imprisonment of two women in Pussy Riot became a cause célèbre of many Western celebrities plus musicians from every genre imaginable:  Bryan Adams, Beastie Boys, the Black Keys, John Cale, Peter Gabriel, Green Day, Nina Hagen, Kathleen Hanna, Paul McCartney, Moby, Yoko Ono, Pet Shop Boys, Red Hot Chili Peppers, Patti Smith, Sting, Pete Townshend, etc.  Pussy Riot was featured on 60 Minutes as well. 

For their part, the bandmembers in Pussy Riot that were not in prison distanced themselves from all of this attention and were quoted as saying:  “We’re flattered, of course, that Madonna and Björk have offered to perform with us.  But the only performances we’ll participate in are illegal ones.  We refuse to perform as part of the capitalist system, at concerts where they sell tickets.”
