Oliveros’s 1980 lecture, “MMM: Meditation / Mandala / Music”, traced some of her musical development by looking at the doodles she was making in the past. Towards the end of the 60s, her sketches featured a variety of electronic symbols and circuit diagrams. By 1969, the electronics had almost entirely disappeared in favour of abstract symbols, circles, spirals and other shapes which she later recognised corresponded to the mandala (geometric representations of abstract or meditational concepts).
