Some context: Can was a German experimental rock band formed in Cologne, West Germany, in 1968 by the core quartet of Holger Czukay (bass), Irmin Schmidt (keyboards), Michael Karoli (guitar), and Jaki Liebezeit (drums). The group cycled through several vocalists, including Malcolm Mooney (1968-70) and Damo Suzuki (1970-73), as well as various temporary members. Drawing from backgrounds in the avant-garde and jazz, Can incorporated minimalist, electronic, and world music elements into their often psychedelic and funk-inflected music. They have been widely hailed as pioneers of the German krautrock scene.
The next few years saw Can release their most acclaimed works. While their earlier recordings tended to be at least loosely based on traditional song structures, on their mid-career albums the band reverted to an extremely fluid improvisational style. The double album Tago Mago (1971) is often seen as a groundbreaking, influential and deeply unconventional record, based on intensely rhythmic jazz-inspired drumming, improvised guitar and keyboard soloing (frequently intertwining each other), tape edits as composition, and Suzuki's idiosyncratic vocalisms. Czukay: "(Tago Mago) was an attempt in achieving a mystery musical world from light to darkness and return."  In 1971 the band composed the music for the three-part German-language television crime mini-series Das Messer ("The Knife"), directed by Rolf von Sydow. The track used was "Spoon".  Tago Mago was followed in 1972 by Ege Bamyasi, a more accessible but still avant-garde record which featured the catchy "Vitamin C" and the Top 10 German hit "Spoon". Czukay: "We could achieve an excellent dry and ambient sound... [Ege Bamyasi] reflects the group being in a lighter mood."  It was followed by Future Days in 1973, which represents an early example of ambient music, as well as including the pop song "Moonshake". Czukay: "'Bel Air' [the 20 minute-long track which took up the whole of side two on the Future Days original vinyl LP] showed Can in a state of being an electric symphony group performing a peaceful though sometimes dramatic landscape painting."  Suzuki left soon after the recording of Future Days to marry his German girlfriend, and become a Jehovah's Witness. Vocals were taken over by Karoli and Schmidt; however, after the departure of Suzuki, fewer of their tracks featured vocals, as Can found themselves experimenting with the ambient music they had begun with Future Days.

Some context: Judy Chicago (born Judith Sylvia Cohen, July 20, 1939) is an American feminist artist, art educator, and writer known for her large collaborative art installation pieces about birth and creation images, which examine the role of women in history and culture. By the 1970s, Chicago had founded the first feminist art program in the United States. Chicago's work incorporates a variety of artistic skills, such as needlework, counterbalanced with labor-intensive skills such as welding and pyrotechnics. Chicago's most well known work is The Dinner Party, which is permanently installed in the Elizabeth A. Sackler Center for Feminist Art at the Brooklyn Museum.
In 1970, Chicago decided to teach full-time at Fresno State College, hoping to teach women the skills needed to express the female perspective in their work. At Fresno, she planned a class that would consist only of women, and she decided to teach off campus to escape "the presence and hence, the expectations of men." She taught the first women's art class in the fall of 1970 at Fresno State College. It became the Feminist Art Program, a full 15-unit program, in the spring of 1971. This was the first feminist art program in the United States. Fifteen students studied under Chicago at Fresno State College: Dori Atlantis, Susan Boud, Gail Escola, Vanalyne Green, Suzanne Lacy, Cay Lang, Karen LeCocq, Jan Lester, Chris Rush, Judy Schaefer, Henrietta Sparkman, Faith Wilding, Shawnee Wollenman, Nancy Youdelman, and Cheryl Zurilgen. Together, as the Feminist Art Program, these women rented and refurbished an off-campus studio at 1275 Maple Avenue in downtown Fresno. Here they collaborated on art, held reading groups, and discussion groups about their life experiences which then influenced their art. All of the students and Chicago contributed $25 per month to rent the space and to pay for materials. Later, Judy Chicago and Miriam Schapiro reestablished the Feminist Art Program at California Institute of the Arts. After Chicago left for Cal Arts, the class at Fresno State College was continued by Rita Yokoi from 1971 to 1973, and then by Joyce Aiken in 1973, until her retirement in 1992.  Chicago is considered one of the "first-generation feminist artists," a group that also includes Mary Beth Edelson, Carolee Schneeman, and Rachel Rosenthal. They were part of the Feminist art movement in Europe and the United States in the early 1970s to develop feminist writing and art.  Chicago became a teacher at the California Institute for the Arts, and was a leader for their Feminist Art Program. In 1972, the program created Womanhouse, alongside Miriam Schapiro, which was the first art exhibition space to display a female point of view in art. With Arlene Raven and Sheila Levrant de Bretteville, Chicago co-founded the Los Angeles Woman's Building in 1973. This art school and exhibition space was in a structure named after a pavilion at the 1893 World's Colombian Exhibition that featured art made by women from around the world. This housed the Feminist Studio Workshop, described by the founders as "an experimental program in female education in the arts. Our purpose is to develop a new concept of art, a new kind of artist and a new art community built from the lives, feelings, and needs of women." During this period, Chicago began creating spray-painted canvas, primarily abstract, with geometric forms on them. These works evolved, using the same medium, to become more centered around the meaning of the "feminine". Chicago was strongly influenced by Gerda Lerner, whose writings convinced her that women who continued to be unaware and ignorant of women's history would continue to struggle independently and collectively.
