The final chapter of the museum’s “Trilogy of Matter” exhibition series, “A Leap into the Void” opens at GAMeC in Bergamo, Italy, to examine “Art beyond Matter.” Interested in artistic acts of “dematerialization” that explore the void as an “ideal or imaginative dimension,” curators Lorenzo Giusti and Domenico Quaranta gather works from nearly 50 luminaries from the historical avant-garde (Alison Knowles, Vera Molnar, Nam June Paik, Yoko Ono) to today’s (JODI, Eva & Franco Mattes, Trevor Paglen, Rachel Rossin, Hito Steyerl).
