Task: Explanation
Input (English): George Balanchine to Antonio Vivaldi's "Concerto Grosso in B minor" and the first movement of his "Concerto Grosso in E major", Op. 3, nos. 10 and 12, respectively; in 1976 he added Arcangelo Corelli's "Sarabanda, Badinerie e Giga", second and third movements. The premiere took place on November 21, 1957, at City Center of Music and Drama, New York, with lighting by Mark Stanley. The original version placed the musicians on stage with a square dance caller calling the steps; from its 1976 revival the caller was eliminated, the orchestra placed in the pit, and a solo added for the "premier danseur" to the Corelli "Sarabanda". The Pacific Northwest Ballet restored the caller for one performance at the 2007 Vail International Dance Festival. Question: Which Italian composer did George Balanchine add in 1976?
