Tangente 1 is the first in a series of exhibitions that invites artists to create new work in response to a corpus of photographs selected from the Canadian Centre for Architectures collection. In a provocative installation, Quebec artist Alain Paiement juxtaposes a wide range of photographic subjects from the collection--buildings under construction, models of student work, architectural abstractions, different levels of transparency--with his own imagery of the new Palais des Congres de Montreal.
