Was that a Broadway show or a rock concert? With electric guitars and amplifiers onstage and actors shouting (or screaming) lyrics, there’s an increasingly fine line between musicals and high-caliber jam sessions.
Of course, high-octane musicals aren’t an entirely new phenomenon. Rock became part of the musical theater scene back in the ’60s, with the premiere of Hair. Ever since, rock musicals have been on and off the Broadway listings; notable examples of the form include Jesus Christ Superstar, Grease, and Little Shop of Horrors.
