In this week's batch of concert photos, two New York–area events represent. On the indie side of things: the Northside Festival, which took over Williamsburg with sets from Mr. Dream, the Suzan, Wavves, Thee Oh Sees, Surfer Blood, Guided by Voices, and more. On the subcontinental-piece-of-land side of thing: Governors Ball, which took over Governors Island with sets from Das Racist, Big Boi, Neon Indian, and more. And in between, photos from Katy Perry, Kid Cudi, and others. Enjoy!
