If you thought Cloverfield had a lock on this year’s prize for the most screams on celluloid, you didn’t reckon with the Hannah Montana/Miley Cyrus crowd. A stage techie describes it best: Listening to several thousand shrieking preteen girls is like sticking your head behind a jet engine. Bruce Hendricks captures last year’s kinetic stage spectacle in breathtaking computerized 3-D; you actually flinch when a drumstick spins toward you. Behind-the-scenes vignettes include tour producer Kenny Ortega’s flamboyant dance demonstrations and footage of burly men sprinting in high heels to win concert tickets. Take your daughter—and your earplugs.
