DecameronTV gets spooky with a series of “Halloween Specials,” bringing together five artists whose practices both commemorate and complicate the spirit of the Allhallowtide season. The artists use ghosts, monsters, costumes and the uncanny as strategies to remember the faithful and unfaithful departed, disinterring themes of family, colonialism, camp, and terror. Participating artists include Charlie Mai, Kembra Pfahler, Marnie Weber, Bri Williams, and Kandis Williams.
