シンフォニーホール
Some of Koussevitzky's later recordings, including performances of the second suite from Prokofiev's "Romeo and Juliet" (1945, Symphony Hall, Boston), first symphony (1947, Carnegie Hall, New York, a session that included Mendelssohn's "Italian" Symphony), and fifth symphony (1945, Symphony Hall, Boston), were reportedly mastered on RCA's sound film optical recording process, first employed in this way with the San Francisco Symphony in March 1942.
