Featured Review: Maturity and Its Muse The only two traits shared by the artists in this wildly eclectic show of sculpture, painting, drawing, photography and then some is that they're based in St. Louis and on the other side of age 70. And they wear these aspects well. As the first exhibition by the new, locally based nonprofit of the same name (which aims to support positive and productive aging through creativity in the arts), M and Its M has managed to gather a deeply accomplished group of individuals whose biographies and personal accomplishments alone could have provided substance for an exhibition. But the art does not fail to deliver, ranging from quilts made of neckties to drawings of roaring orangutans to beak-shaped ceramic pitchers to colorful pop collages to gold chain-mail chokers. Confident diversity is apparently at the heart of growing old gracefully — a message that addresses art's durability or its importance in keeping us young. Through February 5 at the Sheldon Art Galleries, 3648 Washington Boulevard; 314-533-9900 or www.sheldonconcerthall.org. Hours: noon-8 p.m. Tue., noon-5 p.m. Wed.-Fri., 10 a.m.-2 p.m. Sat.
