The first thing you see in the group exhibition Making Mends is a cloud rising from gallery floor to ceiling. It’s a mushroom cloud, but it’s so fluffy that it beckons anyway, and when you get close, you see a ladder dangling down, inviting you up as into a tree house. The stated theme of Making Mends is art and healing, so you know that this sculpture (Playhouse, by Dietrich Wegner), despite its darkness and horror, wants to make you feel better. The whole show is like this: an effective invitation to be moved by art’s ability to respond to the awfulness it cannot change. This art is made of sand, feathers, clay, paint, video. The artists are people who are dying soon, or later, or who have gone to war and are making paper out of their uniforms. Don’t skip this show.
