Luminaria, the annual multi-disciplinary arts fest in San Antonio, has hired it’s first full time executive director, luring Kathy Armstrong, director of exhibitions at the Southwest School of Art in San Antonio into a three-year contract. Luminaria will be seven this year, and Armstrong is looking for ideas to shake up the erratic “Festival of Lights”, including an open call for proposals for this year’s event, scheduled for Oct. 23 and 24.
