Death, ecstatic life, and the potential of the human spirit—these are a few of the monumental themes that the protean artist Matthew Day Jackson addresses in his work, which can range from delicate mechanized wall pieces to colossal, raw sculptural installations. All of these are now on view in his new solo show at Hauser & Wirth's leviathan of a gallery on 18th Street, with a spectrum of double-barreled art that includes multiple casts of his own skull and a 21st-century recreation of Rodin's Burghers of Calais.
