I went to my first concert around 1976. Lynyrd Skynyrd and Atlanta Rhythm Section at the Miami Jai Alai Fronton. Since then I've been to well over a hundred and over the years I've tried many times to bring in a SLR film camera and almost always I've been turned away at the door by security due to restrictions placed by the performer, promoter or venue. They certainly had the right to do so and it was easy for them to enforce it.
Around 1998 Motley Crue came to Orlando for their Bootleg Tour and lifted the no photography restriction to allow anyone with a still or video camera almost all access. Somewhere I have about 6 VHS-C tapes of classic Crue and the strippers coming in to see them
Anyway, no photography at concert venues has been the norm up until cameras came in cell phones and it became to hard to police it. Looks like they are working on a solution to gain back control of their property.
