How will increasing variety of music help much. I ask that because as the cities in the region grows, so do the options. I've mentioned this before. NWA has an amp that's basically Walmart's baby. They will cover the cost of larger acts to play that venue and keep it very active. Here's some names announced so far for it this outdoor season
Kenny Chesney
Dave Matthews Band
Chicago
Steve Miller Band
Brantley Gilbert
Not to mention the second installment of Thunder on the Mountain down on the Pig Trail
That's got Carrie Underwood and Zac Brown Band headlining

And... there's the surrounding casinos bringing in acts like Hard Rock in Tulsa from ZZ Top to Loretta Lynn
In duck hunting, we call that short stopping. Missouri is notorious of spreading out corn in their waterfowl rest areas to hold ducks in the area longer. That effects the need for them to Migrate further south or just to look around in the local area till froze out. You got lots of things now short stopping folks for music now. It's only going to get worse. The Quapaw have bought land along the Arkansas River in Little Rock, ancestral land, in the effort to build a casino. The recent ruling they got concerning the Kansas land that adjoins their casino outside Joplin bodes well for that endeavor. If Castle Rock gets their permit from Kansas, they are going to have an arena as part of theirs. Again, this is not suggesting Branson needs casinos but that has been and is what's hurting Branson with
the older segment that really helped prop up the theater scene. That's not to say Branson can't still have music or a much wider variety of it. I'd love of SDC to bring in a B lister midweek outside of the bluegrass fest to prop up numbers as weekends need no help. It's value added.
To answer you question from my perspective as someone who is outside the area. I think the poster was talking about more permanent entertainment options. Let's face it Branson acts leave a lot to be desired for the younger set. Heck, they leave a lot to be desired for me in my 50's. I am not going to travel to NW Arkansas for a amphitheater show. It is just to far. Branson and SDC pull a lot of tourist from outside this area you have elaborated on. So, for those who come from SE Missouri , Kentucky, Tenn , Illinois and so on your NW Arkansas stuff is irrelevant to us. We can catch that kind of touring act closer to home. It is the nighttime local stuff that is short in the saddle. Now, if Branson were to have some 2 or 3 day music festivals covering all genres from Rap to Gospel than that is a different story.
