Here are my thoughts, which pretty much concur with my wife's.
I had listened to the numerous samples online (and purchased both their cd's after the show), and I'd say I really like about 2/3 of their stuff...the faster, punkier country stuff on the new one, and the alt-countryish stuff on the first one...and don't care much for when they veer into slow song or non-alt-country stuff (They introduced the worst song of the night as "This is our emo song."...though it wasn't really emo.
Anyway, they're guys in their early 20's with a lot of potential. But they aren't there yet. Right now, they're lacking stage presence, and their song selection managed to incorporate more of the songs that I don't like and less of those that i do. At times they sounded like the Truckers or Slobberbone...that's when they were at their best.
And the lead singer (ironically) wore a Travis Tritt t-shirt, and had the same hairstyle as me.
So overall, maybe a B or B- show...flashes of excellence, but still need for quite a bit of growth.
