The art of Howardena Pindell makes for an explorative journey of the difficulties she encountered as an artist of color in the US, yet this is all wonderfully retraced in her current retrospective held at MCA Chicago. Entitled What Remains to Be Seen, the exhibition shows how her artistic experimentation is deeply rooted in the interaction she observes between dots and grids, two elemental forms she has used since the Space Frames she started with as an artist in the late 1960s.
