12 Shouts to the Ten Forgotten Heavens is a ritual cycle consisting of 12 one-day performances at the Whitney Museum of American Art, written and conceived by Sibyl Kempson.

Each performance occurred on the Spring and Fall Equinoxes and Summer and Winter Solstices, beginning in March 2016 and going through December 2018. 

Ralph Lemon recommended 12 Shouts in the August 2016 issue of Art in America.
