RUSCHA AT THE MODERN: Earlier this week, we pointed you to a Wall Street Journal interview with artist Ed Ruscha. He’s the focus of a splashy new show at the Modern Art Museum of Fort Worth called, “Ed Ruscha: Road Tested.” The show opens on Sunday, but Gaile Robinson got a sneak peek. In her dfw.com review, she says that Ruscha’s images of gas stations and other elements of the open road feel right at home. “His pieces are not deliberately complex; if anything they are often funny or so familiar as to seem like family. But they are not as easily interpreted elsewhere. In Texas, his road work seems perfectly natural.”
