Question: 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.

While at UCLA, she became politically active, designing posters for the UCLA NAACP chapter and eventually became its corresponding secretary. In June 1959, she met and became romantically linked with Jerry Gerowitz. She left school and moved in with him, for the first time having her own studio space. The couple hitch hiked to New York in 1959, just as Chicago's mother and brother moved to Los Angeles to be closer to her. The couple lived in Greenwich Village for a time, before returning in 1960 from Los Angeles to Chicago so she could finish her degree. Chicago married Gerowitz in 1961. She graduated with a Bachelor of Fine Arts in 1962 and was a member of the Phi Beta Kappa Society. Gerowitz died in a car crash in 1963, devastating Chicago and causing her to suffer from an identity crisis until later that decade. She received her Master of Fine Arts from UCLA in 1964. While in grad school, Chicago's created a series that was abstract, yet easily recognized as male and female sexual organs. These early works were called Bigamy, and represented the death of her husband. One depicted an abstract penis, which was "stopped in flight" before it could unite with a vaginal form. Her professors, who were mainly men, were dismayed over these works. Despite the use of sexual organs in her work, Chicago refrained from using gender politics or identity as themes. In 1965, Chicago displayed work in her first solo show, at the Rolf Nelson Gallery in Los Angeles; Chicago was one of only four female artists to take part in the show. In 1968, Chicago was asked why she did not participate in the "California Women in the Arts" exhibition at the Lytton Center, to which she answered, "I won't show in any group defined as Woman, Jewish, or California. Someday when we all grow up there will be no labels." Chicago began working in ice sculpture, which represented "a metaphor for the preciousness of life," another reference towards her husband's death. In 1969, the Pasadena Art Museum exhibited a series of Chicago's spherical acrylic plastic dome sculptures and drawings in an "experimental" gallery. Art in America noted that Chicago's work was at the forefront of the conceptual art movement, and the Los Angeles Times described the work as showing no signs of "theoretical New York type art." Chicago would describe her early artwork as minimalist and as her trying to be "one of the boys". Chicago would also experiment with performance art, using fireworks and pyrotechnics to create "atmospheres", which involved flashes of colored smoke being manipulated outdoors. Through this work she attempted to "feminize" and "soften" the landscape. During this time, Chicago also began exploring her own sexuality in her work. She created the Pasadena Lifesavers, which was a series of abstract paintings that placed acrylic paint on Plexiglas. The works blended colors to create an illusion that the shapes "turn, dissolve, open, close, vibrate, gesture, wiggle," representing her own discovery that "I was multi-orgasmic." Chicago credited Pasadena Lifesavers, as being the major turning point in her work in relation to women's sexuality and representation.

Question: At the Drive-In is an American post-hardcore band from El Paso, Texas, formed in 1994. The band currently consists of Cedric Bixler (vocals), Omar Rodriguez (guitar, vocals), Paul Hinojos (bass), Tony Hajjar (drums) and Keeley Davis (guitar, vocals). After several early line-up changes, the band solidified into a five-piece, consisting of Bixler, Rodriguez, Jim Ward, Hinojos and Hajjar. At the Drive-In released three studio albums and five EPs before breaking up in 2001.

At the Drive-In's style is usually described as post-hardcore. Their sound has also been called punk rock, emo and art punk. Some of the group's influences are Indian Summer, Swing Kids, Fugazi, Sunny Day Real Estate (referred to by Ward as "Fugazi beyond Fugazi"), Bad Brains, and the Gravity Records-led post-hardcore sound of the 1990s that featured acts such as Antioch Arrow and Heroin. In their last period before their initial breakup, the biggest influences of At the Drive-In included bands such as Drive Like Jehu and The Nation of Ulysses, with frontman Bixler-Zavala going on to say that "there would be no Relationship of Command without Drive Like Jehu." The band also performed cover versions of songs such as "This Night Has Opened My Eyes" by The Smiths and "Take Up Thy Stethoscope and Walk" by Pink Floyd, both included in the 2004 compilation This Station Is Non-Operational. Their name was taken from the fact that Bad Brains took their name from the Ramones' song "Bad Brain" (from Road to Ruin), and Bixler liked the Bad Brains' song title "At the Movies" (track featured in Rock for Light); while Ward liked "at the drive-in", and his suggestion would eventually win out. Though In/Casino/Out was recorded live, "Relationship of Command may very well be the first record to harness the chaotic balance of adrenaline and intellect of ATDI's live performance." "Ross was instrumental in bringing out a lot of feeling from us," Bixler recalls. "We channeled a lot of emotion into this record. He pushed us farther than we thought we could go. I learned to cut loose the way we do live and not to be afraid to break something or whatever." While capturing the essence of ATDI's live shows in a way never before seen, the record also featured some of the band's most experimental songs, including "Rolodex Propaganda," "Non-Zero Possibility," and "Invalid Litter Dept." The band's guitar-playing, in the majority of their songs, is characterized by unusual chords, a fast tempo, and a quiet-loud-quiet song structure. While Jim and Paul provided the rhythmic structure of the song, Omar often played more experimental riffs and melodies over the top. Effects were heavily used by Omar, especially on Relationship of Command, while Jim used the keyboard to create melody, often switching between the guitar and keyboard such as in "Invalid Litter Department."
