“By Candlelight” concerts

I’m getting these advertised to me all the time at the moment, they seemed like slightly overpriced cover bands and after a quick glance at a Springsteen one in a cathedral the AI generated description and no mention of who would actually be singing turned me off.

Then I noticed it was advertised as “tickets from £14.50” but those are only the seats at the side described as having no view of the performance and any seat where you can see it is a minimum of £45.

Has anyone been to one, what’s the deal with them? It seemed a bit scammy, but maybe that was just this one.
