Andrea Büttner

Opening Saturday: Gone are the days when artists chose a medium — say, painting or photography — and stuck with it. Now they're more likely to pick a medium to suit the project, as German-born Andrea Büttner does in her new solo show opening Saturday at Walker Art Center. Expect to find films, photos, textiles, sculpture, collage, etchings, screenprints and woodcuts, like "Piano," shown here. Or perhaps paintings-on-glass or even a small moss garden growing in a box. She uses all these varied media to explore ideas about such unlikely subjects as the relationship between art and religion, or deviance, poverty, shame and vulnerability. Büttner, who divides her time between studios in Frankfurt and London, will be in the Twin Cities this weekend to discuss her work and complete a new installation commissioned by the Walker. She'll give an artist's talk at 2 p.m. Saturday that's free with gallery admission. (Nov. 21-April 10 at 11 a.m.-5 p.m. Tue.-Wed. & Fri.-Sun., 11 a.m.-9 p.m. Thu. $9-$14; free for 17 and younger and for all on Thursday evenings. Walker Art Center, 1750 Hennepin Av. S., Mpls. 612-375-7600 or walkerart.org)
