Price's career climaxed on September 16, 1966, when she sang Cleopatra in Antony and Cleopatra by American composer Samuel Barber and conducted by Thomas Schippers, commissioned to open the Met's new house at Lincoln Center. The role of Cleopatra was written especially for Price. Since their early collaborations, Price and Barber had remained close friends and colleagues, and the composer tailored Cleopatra's music to Price's warm middle register and soaring top.  In the performances, although Price's singing was praised, especially in a powerful death scene, the opera as a whole was widely considered a failure. Director Franco Zeffirelli was blamed for burying the music under heavy costumes and huge scenery. Bing admitted he had underestimated the challenge of mounting nine new productions that season (three in the first week), and relying heavily on untested high-tech equipment. (In rehearsals, an expensive turntable broke down and, in the dress rehearsal, another mechanical failure left Price trapped briefly inside a giant pyramid.) The pressures and many of the glitches were chronicled by cameras for a Bell Telephone Hour special documentary, directed by Robert Drew.  Still others complained that Barber's score was difficult to grasp because of the dense Shakespearean verse, and lacked satisfying set pieces (apart from the death scene). The opera was never revived at the Met. However, with the help of Gian Carlo Menotti, Barber later reworked the score for successful productions at the Juilliard School and the Spoleto Festival in Charleston, where it received praise. Barber also prepared a concert suite of Cleopatra's arias, which Price premiered in Washington in 1968 and subsequently recorded. Price lobbied Kurt Herbert Adler to have it produced in San Francisco, but did not succeed.
