Cardioid // is a meditation on the life and archived work of Malachi Ritscher by Jennifer Gutowski and Fred Lonberg-Holm. The installation consists of an array of ceramic simulacra of Ritschers's favorite microphone suspended in and defining the space by outlining the polar pattern of that microphone, and an audio component drawn randomly from files taken from the Malachi Ritscher Collection in the Creative Audio Archive, and organized according to numeric data significant to Ritscher's life.
