Smart, sympathetic and ensconced in plaid, Placid Baby refuses to take itself too seriously. Jennifer Allen, Sam Kim and Tania Varela Ibarra move to the riffs of Japanese pop, 70’s Kraut rock, and other musical surprises without inhibition, managing to cover a colossal range of action and reaction. With unflappable vitality, this show keeps on moving and developing into one gigantic THING in which irony and sincerity conspire to evoke empathy.
