Perrotin’s Paris gallery at 76 rue de Turenne is presenting ”Hartung 80,” an exhibition of the artist Hans Hartung, spread across seven sectors looking at form and technique. Through a selection of work focused within the 1980s, viewers will experience the product of Hartung’s “late period,” which—to the surprise of many—proved to be some of the artist’s most engaging artwork due to his use of technical experimentation. The show is presented simultaneously with “Rothko — Hartung: A Multiform Friendship,” on view at 10 impasse Saint-Claude through July 31.
