Brooklyn Museum’s massive new fall show, “Who Shot Rock & Roll,” is a sprawling and captivating look at the last 60 years of American popular music as seen through the lens — or, more accurately, the lenses — of some of the world’s greatest photographers. An entire section devoted to “performance” helps capture the essence of a rock and roll show through iconic photos of Jimi Hendrix burning his guitar, the Ramones surrounded by teenage boys on stage at CBGB, Tina Turner contorting, Ike Turner glaring at her, Janis Joplin spilling out of her dress, and Paul Simonon smashing his ax during a Clash show.
