Around 10:30PM on Wednesday night, the sweaty, median-age-40 crowd at Barclay's Center — arguably the swankiest sports venue in the country — stood up from their folding chairs, raised their fists, and for a moment they felt a little punk rock. On stage were Nadezhda Tolokonnikova, 24, and Maria Alyokhina, 25, former members of the Russian punk feminist collective Pussy Riot dressed in matching black-and-gray dresses. They looked healthy, fearless, and angry as they led the audience in a chant. "Russia will be free! Russia will be free! Russia will be free!"

No doubt much of the audience at the $65 show was there to see Lauryn Hill or Imagine Dragons, two of the artists who participated in the star-studded benefit concert put on by Amnesty International. Susan Sarandon, Wayne Coyne of The Flaming Lips, Tegan and Sara, and Bob Geldof, the musician and star of Pink Floyd's The Wall, also made an appearance.
