The traditional story of Heidi is smothered in rustic innocence-the alpine air, the resilient pines, the cloud-capped peaks carrying purity and redemption. In Mike Kelley and Paul McCarthy's brilliant and truly grotesque retelling, Heidi finds herself in the confines of a mock chalet inhabited by her twisted grandfather and her putative sibling and seducer, Peter. Using life-size dummies, ghoulish masks, and wiggy costumes, the artists, playing off their dummy doubles, depict scenes from the degeneration of a rural-gothic family. Six tableaux obsess on the disciplinary rituals of childhood and the morbid rerouting of sexual drives, but Kelley and McCarthy go beyond the family plot to dramatize desire and the body as perverse social productions. In this compulsive work, nature struggles with nurture in a land where the cuckoo clock has no hands. Not for the squeamish.
