In her 2011 work Venn Diagrams (under the Spotlight), a forerunner toA ∩ B ∩ C, Amalia Pica uses overlapping circles of colored light to refer to her childhood in 1970s Argentina. During this period, the country’s military junta forbade the concept of intersection from being taught in elementary classes, concerned that even its mathematical representation might ultimately prompt citizens to conspire against it. InA ∩ B ∩ C, Pica invites performers to manipulate translucent colored shapes, producing new configurations that, emancipated from the historical anecdote, use abstraction and intersection as an invitation to reimagine forms of collaboration and community.
