Showcase 2: St. Louis Painting and Sculpture Invitational Increasingly, St. Louis galleries are featuring exhibitions of local artists, and it's a very good thing. This show, curated by a panel of St. Louis arts professionals, is the second in a Sheldon series to mark the city's 2004 celebrations. These are some of the area's strongest artists, particularly the painters. Brandon Anschultz, Keith Bueckendorf and Erik Spehn turn in large, sleek abstractions; next to them, Kelly Chorpening's two small ink works on panel brilliantly hold their own. Andrea Green's untitled wall installation is quiet and poignant. The only weak point is the Founders' Gallery, where the show is installed: It's the oddly shaped, narrow area on the first floor, so unremarkable you might walk right past it. Through August 21 at the Sheldon Art Galleries, 3648 Washington, 314-533-9900. Gallery hours 9 a.m.-8 p.m. Tue., 9 a.m.-5 p.m. Wed., 10 a.m.-2 p.m. Sat.
