AST will be performing at the Houston Margarita Festival (HMF) at The Water Works in Buffalo Bayou Park. Time to be announced. Purchase your tickets by visiting www.houstonmargaritafest.com. Bring cash with you on the day of the event. The website says that it's a cash based only event (aside from online ticket purchases). So if you plan on purchasing more drinks after you've had your complimentary drink (comes with your $30 entry), margaritas are $6.00-$8.00.
