"I have listened to plenty of young performers that ask me for bookings, but the vast majority are singer-songwriters who, to me, all sound much the same - and bore me silly! I'm looking for good musicians and singers that are capable of *entertaining* my audience, and if those good musicians and singers are young, that's even better! "

In that case, you cannot complain about diminishing attendance.

If you are booking based on your own tastes, hopefully you have an audience that agrees with you and your shows are heavily attended. If you have no worries, then proceed without a second thought.

IF you are seeing your audience age and attendance shriveling, perhaps you need to step back and reconsider. Your tastes are part of your generation and the style you are accustomed to - and there is nothing wrong with that. However, you may want to consider the fact that there could be an audience for those "boring" singer-songwriters and maybe mixing things up a bit might bring a boost and some faces that have not been around the block so many times.

There is no right or wrong - there only "is".
