“What is M.O.O.T.? A fair question. The very fact that you have this record in your hands means that you are curious and aware that something is happening. M.O.O.T. will show you what it is and where it is.” M.O.O.T. — which stands for Music of Our Time — was a series of records released by Columbia, established by its enlightened president Goddard Lieberson and was intended to be a guide to the electronic music revolution of the late 1960s and early 1970s. The episode features: Morton Subotnick, Steve Reich, Morton Feldman, Robert Ashley, Terry Riley, Richard Maxfield, Pauline Oliveros and Harry Partch.
