New Art on the Walls – and the Floor & Ceiling, Too

Sculpture, which for a while seemed like the ugly stepsister of the arts, is looking more like Cinderella this season. And the belles of the ball are women. Ursula von Rydingsvard, who often works monumentally, piling up archetypal shapes of sawn planks of wood, is the subject of both a show of new work at Galerie Lelong in Chelsea (until October 21) and a display of monumental pieces in Madison Square Park, including a piece in polyurethane resin that looks like some magical, rare crystal grotto (until December 31). Mia Westerlund Roosen, an artist who works plaster in organic, hefty, energetically awkward forms, introduces a new vocabulary of folds and drapery in her first show with Betty Cuningham (until October 14).
