Some sights are unforgettable. Marvin Gaye Chetwynd’s performance Camshafts in the Rain, 2016, produced several such sights, including beetle-like actors wearing enormous colorful paper turbans while stalking around the gallery with the mechanical motions of automatons and a seated Medusa whose head, fringed with giant snakes, rose as a handle was cranked, then collapsed back on her shoulders with a heavy thud. The action was punctuated by moments of silence when the turbaned figures stopped as though glued to the spot. The spectators present the production with the wide-eyed awe of children.
