1968—New York

Leopold Stokowski, in a rehearsal with the American Symphony of Beethoven’s Leonore Overture No. 3, says the following to the principal trombonist: “Do you have an alto trombone? Do you have one? Could we use it in this? I think it has another quality of tone. Alright?” (YouTube excerpt of rehearsal filmed in 1968 at Madison Square Garden concert hall; the excerpt is later used in a 1970 documentary titled, “Stokowski at 88”).
