An ombré hot tub, a bubblegum pink house, gorgeous, multi-colored, woven wall-hangings — Kayne Corcoran Griffin’s current two-person show with Mika Tajima and Jean-Pascal Flavien is chock full of splashy sculptures, paintings, weavings, installations and more that are right up our alley. The two artists are fascinated with the human tendency to gather in groups, and both Tajima and Flavien create playful work that explores what happens at those sites of assembly.
