When Frequent Flyers artistic director Nancy Smith hangs around a place, she does it literally, head in the clouds. As Boulder’s aerial dance maven, she encourages others to do the same. Every August, the scope of her encouragement flies a little higher during the company’s Aerial Dance Festival, which brings an international faculty to Colorado for a mixture of intensive workshops for all skill levels and performances. The nineteenth annual fest swings from the rafters beginning Sunday, July 30, at Frequent Flyers Aerial Dance, 3022 East Sterling Circle in Boulder, with classes getting under way on July 31 for two week-long immersion sessions and a platter of à la carte sessions to choose from in the afternoons. But if you’re just there to watch, Intimate Encounters, $10, at 8 p.m. Monday, July 31, is a great introduction — with talkbacks — to the stars of the fest. Toward the Light, the festival showcase, runs August 4 through 6 at the Dairy Arts Center, 2590 Walnut Street in Boulder; tickets for the mind-blowing performance are $24 to $28.
