yeah its the 7th, i called the place that sells the tickets, they made a mistake on mine and put the 8th. anyways, i haven't been to dos amigos in years but i do know that it is not big so its probable that it is an acoustic set. it also depends if it is indoors or outside, but i am not sure. i know they have many rock concerts there, like hinder was there and i think breaking benjamin, and seether will be there Dec. 13th so i really dont know what kind of set it will be.
