The Southwest School of Art's Fiesta Arts Fair, one of the most family-friendly Fiesta events that support nonprofits, promises to live up to its billing when it welcomes visitors April 20 and 21. The school has curated more than 100 artists locally and nationwide, said Debra Del Toro, Southwest School of Art's director of communications. The fair will also feature live music on two stages, artists' demonstrations, children's activities, and Fiesta food and drink.
