Perhaps it’s a podcast, or a variety show, or a piece of performance art — or all three. Self-described as a “tropical radio art experience,” KunstCapades is hosted by artists Josh Pieper and Tim Sullivan along with their bartender Marv (Robyn Carliss). And although the bi-monthly production is typically recorded in San Francisco, it’s currently in residence at Aggregate Space (801 West Grand Ave., Oakland), where its hosts have transformed the gallery into a combination tiki bar and alpine get away. On March 5, at 4 p.m., Pieper and Sullivan will host a live recording of KunstCapades Episode 32 in the space, complete with tropical cocktails. The guests will be Sarah Hotchkiss, KQED visual arts editor and one of the artists behind Stairwell’s, a walking tour series exploring stairwells around the Bay Area; and Natalia Mount, the recently-appointed executive director of Pro Arts Gallery in downtown Oakland.
