Approximately Infinite Universe is a double album by Yoko Ono, released in early 1973. It represents a departure from the experimental avant garde rock of her first two albums towards a more conventional pop/rock sound, while also dabbling in feminist rock. It peaked at #193 in the United States. The 1997 CD re-issue on Rykodisc added two acoustic demos of songs from this era that were later released on 1981's Season of Glass.
