Not to be redundant, but this event is put together by the "Arizona Zoroastrian Association". This event, however, is not free. The tickets sell for $30 and children less than 5 years old are free. There will be a "Jazz Band" and they will servce "Persian food, pastries and drinks (first one free)". You can purchase tickets through their website www.azaphx.com.
I plan going to this event mainly because I've never experienced any events within the Zoroastrian community. So, this should be a great learning experience and it would be great to experience it with members of our group.
I will appraise you of any changes, if there are any.
