Sommeil: A Concert for Sleep is all-night events in which the audience is asked to attend the concert with a sleeping bag and pillow and to fall asleep while a slowly unfolding sonic texture evolves over the course of the night and into the morning. People attending the event are asked to be willing to sleep during the event or at least to remain silent during the course of the nine hour experience.

Not merely a recreation of Rich’s original idea, Sommeil is a conceptual, global remix of a performance type that addresses one of the most basic functionalities of ambient and environmental sound; music by which to sleep.
