Sculptor and installation artist Johannes Girardoni shows at both PDX Contemporary and PDX Across the Hall. It is clean, modernist-inspired work. His recent pieces are photos of industrial structures strategically blocked out with commercial paint; the work bridges the distinctions between photograph, drawing, and performative intervention. (Of note, Girardoni will show at the 54th Venice Biennale as part of the Biennale Collateral Events.) Opening reception May 5, 6-8 pm.
