My wife and I are interested in attending one of your mariachi performances.  We've attended in the past, but only the Saturday series of performances that were at an outdoor venue, with food and beverages available, and lots of people.  Which day should I plan for, the Espectacular Concert on the 22nd, or the Noche Garibaldi on the 21st?  Also, how can I purchase tickets in advance, as neither Eventbrite nor Ticketmaster seem to have these events on their calendars?  Thank you for your time.
