Constance DeJong (born 1950) is an American artist writer and playwright. She is probably best known as the writer on the libretto of Philip Glass's opera Satyagraha. She is also well known for her numerous collaborations with Tony Oursler on projects such as Fantastic Prayers. DeJong has exhibited internationally with projects produced by organizations such as the Dia Foundation for the Arts and Minetta Brook. She is currently a professor of art and time based media at Hunter College. Most recently, in April, 2008, Satyagraha was put into a new production at the Metropolitan Opera in New York. In 2006 she wrote the text for SuperVision, a collaboration with The Builder's Association which premiered at the Walker Art Center in Minneapolis and at the Brooklyn Academy of Music (BAM) in New York. DeJong's writing is closely tied to performative practice. Her first book, Modern Love, was published in 1977 by Standard Editions. In 1978, this text was adapted into a 60 minute radio program accompanied by the "Modern Love Waltz" a piano composition by Philip Glass. A subsequent work published in 1978, The Lucy Amarillo Stories, was a collection of poetry also read aloud by the artist in a 1977 performance at The Kitchen. Mr. Glass wrote a duet for flute and harmonica, titled 'Lucy's Music', for the Kitchen performances. The music was performed by Richard Landry and Ken Deifik.
