In Dutch, the expression 'een klap van de molenwiek', literally a hit by the windmill, is used to say that someone is a little bit crazy. The title of this work, Quiet Before the Storm, refers to the sensation of spiritual enlightenment described by Dostoyevsky's Prince Myshkin in The Idiot, as preceding an epileptic fit, and the notion of numinous sound (sound of divine origin) put forth by the anthropologist Donald Tuzin during his studies of the Bullroarer cult in Papua New Guinea.
In Quiet Before the Storm an ensemble of rotating rubber bands stretched on wooden crosses is used to create a ritual experience in which audible frequencies and infrasound travel through space and around the perceiver, inducing unordinary psychological states. By employing a prehistoric technique of sound production which predates Pythagorean notions of music and mathematics, Quiet Before the Storm addresses cognitive processes concerning perception and transcendence that escape the boundaries of what can be objectively measured, notated or recorded.
