Igor Stravinsky's Concerto in D ("Basle") for string orchestra was composed in Hollywood between the beginning of 1946 and 8 August of the same year in response to a 1946 commission from Paul Sacher to celebrate the twentieth anniversary of the Basler Kammerorchester (BKO), and for this reason is sometimes referred to as the "Basle" Concerto. It was premiered on January 27, 1947 in Basel by the Basel Chamber Orchestra conducted by Paul Sacher (White 1979, 438).
The Concerto in D was the first composition Stravinsky created after becoming a naturalised American citizen on 28 December 1945, and was also the first of his works to be published under the contract with his new publisher, Boosey & Hawkes (White 1979, 123–25).
The concerto has been choreographed several times as a ballet, first by Dore Hoyer at the Hamburg State Opera in 1950. Later ballet versions were made by Jerome Robbins, under the title of The Cage in 1951, and by Werner Ulbrich, as Attis und die Nymphe at the Württembergische Staatstheater, Stuttgart, in 1959 (White 1979, 439).
