In Salzburg that summer, Price sang her first Donna Anna in Don Giovanni, again with Karajan.[5] She then returned to Vienna to appear first as Cio-Cio-San in Puccini's Madama Butterfly.[citation needed] She was also the soprano soloist in Verdi's Messa da Requiem at the Vienna Festival with conductor Carlo Maria Giulini. It was performed to a sold out crowd at the Konzerthaus, Vienna on June 9, 1960 with Price's fellow soloists including Fiorenza Cossotto, Luigi Ottolini, and Ivo Vinco.[30] She returned to the Vienna Festival in 1963 to portray the title in Tosca with Karajan conducting.[31]
