Of Rage and Redemption: The Art of Oswaldo Guayasamín — This relatively small but extremely powerful exhibition includes not quite 50 paintings and prints and more than two dozen drawings by the great but underexposed Ecuadorian artist Guayasamín, who died in 1999 at age 79. The introduction to the show quotes the artist as saying, "My painting is to hurt, to scratch and hit inside people's hearts. To show what Man does against Man," and that's an all too apt description of how effectively Guayasamín's best work both wounds and illuminates, joining the ranks of Goya and Picasso's Guernica as some of the best sociopolitical art of the 20th Century. (Through December 6 at the Schmidt Center Gallery, University Galleries, Florida Atlantic University, 777 Glades Rd., Boca Raton; 561-297-2661.)
