As a student in the 90s I worked security for the student concert group on campus. We had to frisk people for Jello Briafa (Dead Kennedys) spoken word performance. I found a couple of tape decks, but those were allowed. They still put a lot of effort sometimes. I saw Dave Chapelle in NYC and they made us put our phones in these pouches which were unsealed on exiting the show.
