Two shows vie for the title of ‘most talked about’ this month: young, German maverick John Bock’s new video and zany rooftop installation at Anton Kern Gallery and painter of curvaceous women, Lisa Yuskavage’s latest bevy of babes at David Zwirner Gallery in Chelsea and Zwirner & Wirth uptown. Those who love Bock’s signature mad scientist behavior will delight to find the provocateur slithering through cabinetry, eating from a can of ravioli with a spoon attached to a chair leg and performing other bizarre feats. Likewise, Yuskavage fans will enjoy a spectacular array of light drenched, color-soaked portraits of fecund females. Neither will leave you short of conversation. (John Bock is at Anton Kern Gallery until November 25, Lisa Yuskavage’s paintings are up until November 18.)
