The very few artists who do, and have the creative freedom to so do are probably the only ones who could get away with this. Convention Centers don’t seem to have the same density of existing Ticketmaster relationships, and while they’d have to pay to bring in seating at some, I bet they could do it for something similar to Ticketmaster’s middleman fees.

I’m not sure the difference between costs for concert venues and convention centers, but if it’s anywhere near comparable, it could be feasible.
