Art Detour is back and bigger than ever. This year what was once a weeklong art walk celebrates art not just in Phoenix, but across Arizona, for more than a month. Through March 31, Art Detour will feature more than 300 arts activities and connect art lovers with special shows at art galleries, arts and culture organizations, arts-supporting businesses and visual and performing artists. The annual event is put on by Artlink Inc., a nonprofit that supports local artists, art initiatives and events including First and Third Fridays. “We want these 33 days to feel completely different from any other set of 33 days,” said Catrina Kahler, Artlink president and CEO.
