For six weeks in 2010, artist Tino Sehgal’s work, “This Progress” took over the Guggenheim Museum. Visitors enter the space only to find the iconic ramps of the building completely devoid of physical artwork. Each group is accompanied up the ramps by several guides, referred to as “interpreters,” of various ages, beginning with a child and ending at the top with a senior. Along the way visitors are asked a variety of questions and encouraged to engage with their guides. This engagement is taken even further thanks to the rules set in place by the artist: no photos, no videos, and no recording of the work. Due to the individualized subjectivity of the piece, each experience has the potential to vary drastically; “This Progress” puts the art spectator on equal ground with Sehgal’s work, calling into question the usual heirarchical relationship between viewer and piece.
