Approximately Infinite Universe

Approximately Infinite Universe is the third solo album by Yoko Ono, released in early 1973 on Apple Records. A double album, 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 number 193 in the United States.

The album was recorded at The Record Plant in New York City, except for the basic tracks for "Catman" and "Winter Song", which were taped at Butterfly Studios. Ono produced the album with John Lennon, whose participation marked a rare music-related activity for him after the failure of the couple's politically themed 1972 double album Some Time in New York City. Lennon also sang the final verse of the song, "I Want My Love to Rest Tonight". As on the latter album, Ono used the New York band Elephant's Memory as her backing musicians. Mick Jagger dropped into the studio for some of the sessions. He recalled playing guitar very loudly with Lennon. Jagger also said that Ono "was really trying to sing properly. She's not screaming, she's really trying to sing."

The inside gatefold sleeve contained Ono's essay "The Feminization of Society". An abridged version of this essay was previously published in The New York Times in February 1972. The full essay was published in Sundance Magazine in May 1972.
