Bruce Nauman: Untitled (LEAVE THE LAND ALONE)

From the Armoury Center for the Arts website

The sky above the Arroyo Seco will be transformed by a never-before produced work by noted American artist Bruce Nauman. This major work takes the form of skywriting that will say, in Nauman’s classic humor, ‘Leave the Land Alone.’ Nauman developed this project for an exhibition about Earth Art in 1969 but it was never produced. The Armory Center for the Arts brings Nauman’s art back to Pasadena where the artist once lived and worked. This performance marks his first solo institutional project in the Los Angeles area since 1994.
