Is my daughter old enough?

In July Carrie Underwood is coming in concert to our town. My six year old LOVES Carrie Underwood and almost dies every time we drive past the billboard begging to go. I don't know if she's old enough to go to a concert yet or not. It's a seated concert at a college, the college is BYU and if anyone knows anything about this college they would understand that they're not even going to serve beer there because it's such a religious school and town. What do you all think should I buy the tickets and surprise her at her Kindergarten graduation or is she still a little young to attend an event like this? Oh and then after because it's on July 3 there will be a huge firework display as well. . .
