Regan Rosburg hopped onto the Biennial of the Americas bandwagon to curate Axis Mundi: Environmental Melancholia, Collective Social Mania, and Biophilia, an expansion of the artist’s own previous ecological-statement works and a multi-leveled satellite event in itself. Axis Mundi kicks off with a screening of Albatross, a film by Chris Jordan that meticulously examines the grim life and death of birds on Midway Atoll in the Pacific, at 7 p.m. Thursday, September 14, at the Sie FilmCenter, 2510 East Colfax Avenue. Then the three-part Axis Mundi show opens with a reception from 6 to 9 p.m. Saturday, September 16, in a trio of Curtis Park locations — PlatteForum, 2400 Curtis Street; the Olympic Building, 2565 Curtis Street; and the Land Library, 2612 Champa Street — where the works will be displayed through October 7. All events are free, but advance reservations for the film are required at eventbrite.com. For more information, visit axismundiartistsrespond.wordpress.com.
