Ay-Ō’s Happy Rainbow Hell is the first American museum show for the ninety-two year old, Tokyo-based Fluxus artist who ceased art-making in 2017, though he is a veteran of tributes in his native Japan. Centering around eighty rainbow serigraphs the museum has acquired, this treasure trove creates an ideal port of entry for a presentation by Assistant Curator of Japanese Art, Kit Brooks, to the little-explored, contemporary yet timeless Ay-Ō Flux-story.
