Not really. The vast majority of live music isn't even able to sell tickets as nobody would pay a penny, let alone a fortune. Getting in isn't much of a problem.

Only the megastars that can command high-priced tickets would attract the old and square, which is okay because the megastars are old and square themselves by the time they've built that old and square audience. The hip and with it music fans have already moved on to seeing the next up-and-comers that play for free.
