got a little bit of info... they emailed this to me:
"Yes. All of our shows are open to the public. If you are 18 or older, you can buy a ticket at the door. The show will be a benefit concert, so the price is $10. Please note, if you are under 18 and you want to attend,
You must bring your parent or guardian. Our staff and volunteers CANNOT give you permission to attend. Hope that helps."
YAY!
