A music performance in front of an audience is audiovisual. You would be right if we were talking about a photograph of a radio taken while the performance was broadcast, but we're not. Indeed, when people mention they attended a concert, they say things like 'I went to see my favorite band last week,' as opposed to saying they went to listen to them.

wikimedia itself observes that shoting without a permit may put you in breach of a contract you signed when you purchased the ticket, as I alluded to above:

...which is why publishers won't buy photographs without a signed release, such as this one:
