Here’s my post on Pentimenti. Here it is in this week’s Weekly. Working with six local artists new to her gallery, Pentimenti’s Christine Pfister organized Think Global, Go Local as a show about relationships. It’s an exhibit of clean, sleek, beautiful work consistent with the gallery’s aesthetic and has two surprises — an architectural piece that bulges like a pregnant wall of a house and two sculptures that puncture a freestanding gallery wall, their “heads” on one side and “tails” on the other.
