You didn't put dates, so I'm not sure which wkend you're talking about. Last year Vegas had 2 events a week apart. But maybe this link will help some:
www.tejanoticket.com
Friday, July 14 - Mingo Saldivar w/Guest Ms. Linda Escobar
and I see Evolucion has it on their myspace calendar, but I don't see them on the website.
