Contributed by Lucas Moran / Making sense of art is not easy. You can’t pin down meaning when it keeps moving. Darren Bader’s new show “Youth,” now on view at Matthew Brown Gallery, vividly illustrates the point. Bader has been called a prankster and an absurdist, elevating the ridiculous into high art. His earlier projects included injecting lasagna with heroin, stuffing a brass instrument with shrimp, and giving away live kittens. He provides bits of text that hint at deeper meaning while refusing to settle into it. Filling a gallery with art that plays conceptual games with history and humor and still looks good is no easy trick. But Bader pulls it off.
