The Hammer Museum has an interesting show up now called “Out of the Box,” which features Jacob Samuel’s limited-edition art books. Each book is a collaboration between Samuel and a wide range of artists, from performance artists Meredith Monk and Marina Abramavic (who seems to be everywhere right now) to old California staples Ed Ruscha and John Baldesarri. The work I found most arresting was by Wangechi Mutu, a Kenyan artist whose work always stops me in my tracks. Known for her striking collages, she showed up at Samuel’s place with a bunch of fashion and porn magazines. Her work makes you wonder whether there’s a big difference between the two.
