Freddie Mercury’s skyscraping vocals matched his onstage flamboyance, leading the charge on hits that were never less than anthemic. “Bohemian Rhapsody,” from 1975, packs a thrilling, shape-shifting rock opera into six minutes, with stacked harmonies, squealing metal guitar, and Mercury’s gymnastic vocal leaps. Queen later skillfully switched from rock shuffles (“Crazy Little Thing Called Love”) to funky dance pop (“Another One Bites the Dust”), while punch-the-air anthems such as “We Will Rock You” and “We Are the Champions” soundtracked thousands of goals and touchdowns.
