Yoko Ono

Yoko Ono (born February 18, 1933) is a Japanese-American artist, musician, author and peace activist, also known for her marriage to John Lennon and her groundbreaking work in avant-garde art, music and filmmaking.

Ono brought feminism to the forefront through her music, and is also considered a pioneer and major influence of the 1970s new wave genre.

She is a supporter of gay rights and is known for her philanthropic contributions to the arts, peace and AIDS outreach programs.

Ono was also an experimental filmmaker who made sixteen films between 1964 and 1972, and gained particular renown for a 1966 Fluxus film called simply No. 4, but often referred to as “Bottoms”. The film consists of a series of close-ups of human buttocks as the subject walks on a treadmill. The screen is divided into four almost equal sections by the elements of the gluteal cleft and the horizontal gluteal crease. The soundtrack consists of interviews with those who are being filmed as well as those considering joining the project. In 1996, the watch manufacturing company Swatch produced a limited edition watch that commemorates this film. (Ono also acted in an obscure exploitation film of the sixties, Satan’s Bed.) —Wikipedia
