Throughout her marriage to the musician and composer
John Cage – from 1935 to 1945 – Xenia performed in his percussion ensemble. Cage is believed to have been the "female performer" who smashed a
lime ricky bottle into a can of broken glass at the culmination of John Cage's
Construction in Metal. In 1943, Cage exhibited an abstract mobile in
Peggy Guggenheim's show
Exhibition by 31 Women at the
Art of This Century gallery in New York. The next year, Cage had a solo exhibition of her mobiles at the
Julien Levy Gallery in New York. Cage notably collaborated with artists
Joseph Cornell and
Marcel Duchamp as a bookbinder (she studied bookbinding with Hazel Dreis), and designed a chess table in tandem with a set created by
Max Ernst. By the 1950s, Cage had ceased to publicly exhibit her art, and worked at the
Metropolitan Museum of Art in
New York City and the
Whitney Museum of American Art in
Manhattan. She also worked as a conservator at the
Cooper-Hewitt Museum in New York from 1968. ==Personal life==
