A retrospective of sorts, this exhibition of 30 years’ worth of work and a new public piece could not have come at a better time. Oklahoma artist Edgar Heap of Birds, an enrolled citizen of the Cheyenne and Arapaho tribes, has long lent his critical voice and perspective to contemporary art. Embedded in his approach has been a pointed, ardent practice of challenging viewers to rethink stereotypical notions about Native people. He’s a person and artist resolutely of the present, creating provocative text-based works that—as one critic has said—undertake a form of “symbolic and semiotic warfare.” Also included in this show are the 2012 Neuf paintings, which abstract landscapes through the lens of Cheyenne numeric symbols. A new blue-and-white banner outside the gallery is the most recent addition to his Native Host series, which when decoded brings local Native history into the fraught present.
