"Nothing Is Forever" at the South London Gallery, 65 Peckham Road, London, through September 2, southlondongallery.org

Twenty artists exercise their inner Sol LeWitt in this group show that’s all about drawing, painting, writing on, and creatively altering the walls of the gallery space.

"The Great Unreal" at KUNSTAGENTEN Galerie, Linienstrasse 155, Berlin, Germany, through September 25, kunstagenten.de

Two young Swiss photographers turn their lenses on weird Americana, including "a group of French fries that were assembled as a group of tourists on a cliff at the edge of the Grand Canyon." There are also ghostly, glowing cars and accidental geometric abstractions based on power lines.

"American Documents" at FotoMuseum, Waalse Kaai 47, Antwerp, Belgium, through September 5, fotomuseum.be

Seems like European galleries are fixated on the American scene this summer; this survey brings the photographic visions of Larry Sultan, Lee Friedlander, Diane Arbus, and many others to a Belgian audience.

"Pretty Much Everything: Photographs 1985-2010" at Foam Museum, Keizersgracht 609, Amsterdam, the Netherlands, through September 15, foam.nl

High-concept commercial Dutch photographers Inez van Lamsweerde and Vinoodh Matadin bring an edge to their commissions — as in a work from 2000 in which they defaced Björk. A limited-edition art newspaper is being sold here to accompany the show; it’s produced by red-hot Parisian design team M/M, who reimagined Interview magazine last year.

Charles Ledray, "workworkworkworkwork" at ICA Boston, 100 Northern Avenue, Boston, Massachusetts, through October 17, icaboston.org

Ledray’s sewn installations — such as his miniature men’s suits — are eccentric and precious. For this well-deserved survey he also shows a multi-faceted work in black porcelain.
