The photo on the web site promoting the Mesa Arts Festival makes the event appear more biker rally than art festival. But behind those rows of parked Harleys lurk the colorful canopies covering the sprawling aisles filled with original art and gift items from 38 local, regional and national artists. Works include oil and watercolor paintings, sculptures, drawings, metalwork, jewelry, photography, pottery, ceramics, glass applications, and just about any other medium imaginable. The annual festival also features how-to art demonstrations, children’s activities, and food from local vendors. A varied schedule of live music filling two stages with local and national acts, including Sol Gitana, Celestial Misfits, Dustin Jake, and Sugar Thieves, will keep the joint jumping.
