Allan McCollum reviews his work from the 1970’s to the present and discusses his ongoing obsession with the question of what makes an object an “art object.” McCollum is best known for his multiples, which by sheer power of replication force us to rethink notions of identity and uniqueness. The artist is interviewed by Thomas Lawson. McCollum: “We live in a world filled with substitutions for things that are absent, since every copy, in a certain sense, only exists because the original is gone. So copies are always about something absent, and in that way, they carry a sense of mourning, death, or loss.”
